I pitted my dream PC from 2017 against an RTX 5090 monster in 2026 in a fight to the death - here's what happened

I was fourteen or so when I went to the Gadget Show Live (once a big tech event in the UK which showed off the latest technology) in 2016 as a punter and overheard someone on a stand I'd visited mention they'd spent £1,000 on a custom gaming PC.

A thousand pounds. On a computer. I remember turning that figure over in my head (it's roughly $1,400) and not quite being able to make sense of it, not necessarily because I couldn't fathom how much money that was, but because at the time, it seemed like a lot of money to spend on a PC without any frame of reference as to what that price got you.

As it turned out, £1,000 would have bought you an upper mid-range system back then, and speccing a top-end system of the time would have added an awful lot more to my 'dream budget'. A properly specced 3XS system built around Intel's then-flagship Kaby Lake processor, the Core i7-7700K, and an Nvidia GeForce GTX 1080, would set you back around £1,700 including VAT.

Nvidia went one further with the venerable GTX 1080 Ti, which arrived in March 2017. It immediately became the card every serious PC gamer wanted, and pushed that high price even higher. Nonetheless, you still got an entire top-of-the-range PC for that price.

Here's what's strange about that number in 2026: it's roughly what you'd pay for a flagship graphics card alone. Nvidia's RTX 5090 should retail for roughly in line with what this entire PC cost, although the Asus ROG RTX 5090 Astral I've got for testing is over double the RRP of this PC, even taking inflation into account.

Intriguingly, the GPU that was the ceiling of consumer ambition in 2017 is now, in isolation, cheaper than a mid-range graphics card in 2026. Nvidia's GTX 1080 Ti launched at £699 / $699 (about AU$930); the RTX 5090 launched at £1,799, at least for the Founder's Edition card.

That's not a like-for-like comparison — flagship GPU pricing has always been a law unto itself — but it does tell you something about the economic difference between these two moments in PC gaming history.

Now, Scan has sent me that exact system, and I've plonked the GTX 1080 Ti Founder's Edition inside, and I've been running it alongside my own high-spec rig, with an RTX 5090 added for good measure, to see how the decade-old dream holds up.

What £1,700 bought you nearly a decade ago

Here's the entire spec sheet of the 3XS PC that Scan sent my way with the GPU swapped out:

• CPU: Intel Core i7-7700K
• Cooler: Corsair 240mm AIO
• GPU: Nvidia GTX 1080 Ti Founder's Edition
• RAM: Corsair Vengeance LED 16GB DDR4-3000
• SSD: Samsung 960 Evo 250GB SSD (supplemented with a further 1TB SSD for game storage in my case)
• Motherboard: Asus ROG Strix Z270F Gaming
• PSU: Corsair RM750x 750W White
• Case: Corsair Carbide 400C in white

On first impressions, I'm a fan of the Corsair Carbide 400C case, feeling it to be a quieter and more considered choice than a lot of the RGB-laden alternatives that were becoming increasingly common at the time. Coming in white adds a bit of style to proceedings, and it seems roomy enough for the build on offer here. The hinged door with glass window is a nice touch, too.

Inside, the Asus ROG Strix Z270F Gaming motherboard is decently feature-rich and adds a smattering of RGB in the top corner to sit alongside the white LEDs of the RAM and the stock case fan inside. The Samsung 960 Evo SSD would have been top spec at the time, but is the one component that feels particularly outdated. It's a fast, capable boot drive, but is easily filled up with a modern Windows 11 installation and a game or two. Back in 2017, you'd have definitely wanted a hard drive installed as well.

Then there's the GTX 1080 Ti Founder's Edition. Nvidia's reference cooler on the Ti was a meaningful step up from the blower-style designs of previous generations, with an open dual-fan layout that kept temperatures in check. It's a handsome card even by today's standards and feels more restrained than the AIB partner designs that surrounded it. Holding it in 2026 feels like handling something from a very specific and rather significant chapter in GPU history, given its legendary status.

The 1080 Ti has a reputation that outlasted the hardware cycle it was supposed to belong to. When Nvidia's RTX 2080 Ti arrived in 2018, it brought ray tracing and a steeper price — and offered only a slight bump in rasterisation performance that most 1080 Ti owners looked at the cost of upgrading and decided against it. Even now, folks are asking how good this card is today, which is testament to its performance - and indeed its reputation.

A modern point of reference

Of course, benchmark numbers are no good in isolation, so for comparison's sake, I'm putting the Scan system against my own personal gaming rig, with the added boost of the RTX 5090. Usually it'd be an RTX 4080 Super, but for a 'dream PC' angle, I needed to go with the modern dream. Here it is in terms of specs:

• CPU: AMD Ryzen 7 7800X3D
• Cooler: Noctua NH-D15
• GPU: Asus ROG Astral RTX 5090
• RAM: Corsair Vengeance 32GB (2x16GB) DDR5-6000 CL36
• SSD: Lexar NM790 4TB
• Motherboard: NZXT N7 B650E
• PSU: NZXT C1200 1200W 80+ Gold ATX 3.0
• Case: NZXT H9 Flow (2023)

That isn't too bad of a PC if I do say so myself, and yes, I could use faster RAM or a beefier AMD processor if I wanted to eke out as much performance as possible, but I haven't seen fit to upgrade just yet.

Benchmarking methodology

To see how this 2017-era PC performs in the big 2026, I thought it might be fun to run it through a range of games – both ones that are contemporaries of the system and some slightly more modern titles that might push it quite hard. I've also put it through a range of modern benchmark tests to gauge performance against the newer hardware.

To Scan's credit, the machine came running the latest version of Windows 11 25H2 and Nvidia's latest driver release for GTX 10-series desktop cards, driver 582.66, which was a security update released in June 2026.

I've also elected to run games hooked up to my 4K QD-OLED monitor to see how far we can really push this Scan system, running at 1080p, 1440p and 4K to give you a full picture. The RTX 5090 system has also been put through the same tests, as close as possible, to give some comparable results and a frame of reference.

Testing 2017-era games

Firstly, I thought it was correct to run the Scan system through some games that would be period-correct for the time this PC was released to give an idea of a baseline. All four titles were run at their maximum settings, for reference.

Far Cry 5 seemed an ideal first candidate, being from 2018, and at the Ultra preset with HD textures enabled, it managed a 113fps average at 1080p. Going up to 1440p pushed things to 95fps, proving some surprisingly playable results. It was only when I got up to 4K that things dipped immensely, with a 50fps average. For reference, the RTX 5090 system hit 186fps at 4K, which tells you something about how much the goalposts have moved.

I followed this up with the original Dirt Rally, a game that relies on a strong CPU to help alongside the 1080 Ti, so the Core i7-7700K has to do a fair bit of heavy lifting. At the Ultra preset, the 1080 Ti managed 127fps at 1080p and 126fps at 1440p — results so close together that the GPU clearly isn't the bottleneck at either resolution; the 7700K is setting the ceiling, and it's holding it pretty well. At 4K, the GPU gets more of a say, and results come in at a still-reasonable 79fps.

However, this revealed one of the bigger gulfs between the older system and my more modern option. The RTX 5090 system managed 304fps at 1080p, 267fps at 1440p, and 225fps at 4K — numbers so high they serve as a reminder of how differently the two machines interpret the same game.

The original Hitman, which uses DirectX 12 at maximum settings, returned 128fps at 1080p, 106fps at 1440p, and 59.5fps at 4K. The RTX 5090 system managed 203fps at 1080p, 191fps at 1440p, and 186fps at 4K — again, the gap narrowing considerably at lower resolutions before opening up at 4K.

I'd argue Rise of the Tomb Raider is the 1080 Ti's finest hour in this period-correct lineup. Running at the Very High preset in DirectX 12, it returned 144fps at 1080p and 110fps at 1440p. These are numbers that would have felt sky-high at the time and still feel impressive today. Even at 4K, the 59.7fps result is the most modern-feeling 4K figure of the four period titles, suggesting this is a game the 1080 Ti was particularly well-matched for, and a near-60fps average provides some very playable results even today.

That is, until you get the RTX 5090 involved – it posted 316fps, 302fps, and 281fps across the three resolutions in Rise of the Tomb Raider.

Trying newer games

The older game results paint a flattering picture of the 1080 Ti. However, modern titles are much less kind, as you might expect.

My first port of call was Cyberpunk 2077, perhaps this generation's Crysis equivalent, as it can be quite a demanding title for a range of systems. For the 1080 Ti, at the Ultra preset without any upscaling, it managed 52fps at 1080p — passable, if not quite the experience the game deserves — while 1440p dropped to 32fps, and 4K delivered a deeply unimpressive 13.9fps. Enabling FSR 2.1 Quality improved things to 62fps, 41fps, and 20.5fps across the three resolutions respectively, which at least makes 1080p feel workable.

Beyond that, it's a significant compromise. Ray tracing isn't an option here at all — the 1080 Ti simply has not got the hardware for it, and that means for 2026's most demanding titles, including Indiana Jones & The Great Circle that require hardware-based ray-tracing to even run, you won't be able to play them at all.

The RTX 5090, by contrast, ran the Ultra preset at 173fps, 148fps, and 116fps natively. Plus, a more modern card supplements its raw power with Nvidia's DLSS upscaler and fully-fledged RT performance. With DLSS Transformer enabled, those numbers climbed to 183fps, 170fps, and 167fps. With a combination of Cyberpunk 2077 at its RT: Ultra preset with DLSS Transformer enabled, it managed 130fps, 129fps, and 125fps at 1080p, 1440p, and 4K respectively. The gap between these two machines in Cyberpunk 2077 is the widest in my entire test suite, and the most instructive.

This is especially true when you take the multi-frame-gen tech Nvidia has put into these new Blackwell cards, acting as a multiplier for 'fake frames' for a smoother feeling experience, as long as you're starting with a solid enough base frame rate so too much latency isn't introduced. With the RT: Ultra preset, and the MFG multiplier set to 4x, the RTX 5090 system managed 511fps at 1080p, 452fps at 1440p and 355fps at 4K, widening the gulf even further.

Returnal tells a similar story for this matchup. The Epic preset returned 57fps at 1080p, 45fps at 1440p, and 27fps at 4K — the 1080p result is playable, but Returnal's fast-paced action makes anything below 60fps feel like a handicap, and 27fps at 4K is below any reasonable threshold. The RTX 5090 managed 231fps, 207fps, and 147fps at the same resolutions. In a game built around sharp reactions and split-second timing, that headroom matters more than in most.

Moving over to Rainbow Six Extraction, I had higher hopes for a more modern eSports-type title. The default Ultra preset includes a Dynamic resolution of 25-100% of the selected one, which is how I left it, revealing 126fps at 1080p, 85fps at 1440p, and a genuinely solid 66fps at 4K. It's the most comfortable the 1080 Ti looks across this entire modern test suite, and a reminder that there are modern titles that aren't particularly demanding, which are still playable on older hardware.

Meanwhile the RTX 5090-equipped modern PC scored 461fps at 1080p, 405fps at 1440p, and 272fps at 4K, and prove the benefit of the bevvy of high refresh rate OLED screens we've begun to see in recent years when paired with such powerful hardware.

For one final test, I thought it'd be interesting to try a super up-to-date Unreal Engine 5-based title in Black Myth Wukong, as one of the few titles that doesn't need any hardware-based ray-tracing, unlike a lot of its contemporaries.

I elected to step down to the Very High preset, with FSR enabled (with a resolution scale of 33 for 4K, 49 for 1440p and 66 for 1080p) and frame-gen on. The result was 46fps at 1080p, 44fps at 1440p, and 40fps at 4K, which make for some remarkably consistent numbers across different resolutions that make it clear that frame-gen is doing some form of heavy lifting to keep the output FPS so stable. The RTX 5090 managed 120fps, 122fps, and 119fps with the same settings.

Synthetic benchmark time!

The synthetic benchmarks tell a predictable story. The 7700K holds up reasonably well in single-core workloads — the gap to the 7800X3D is meaningful but not embarrassing, and is somewhere in the region of 50% depending on which test you trust.

Multi-threaded performance is a different matter, though, where nearly a decade of core count increases and architectural progress make the comparison increasingly one-sided.

On the GPU side, the picture is more interesting. In 3DMark Fire Strike — a DirectX 11 test that's broadly representative of the conditions the 1080 Ti was designed around — the RTX 5090 leads by roughly three time. Push to Fire Strike Ultra at 4K, and that becomes nearly five times, and the Time Spy results, which move into DirectX 12 territory, tell the same story: a 4x gap at 1440p becoming 4.6x at the Extreme variant.

The 1080 Ti doesn't just lose ground to newer hardware — it loses it disproportionately as resolution and API demands increase, which is worth keeping in mind as we come to a judgement on this entire system.

Summing up

The comparisons made here make for a fascinating reminder of just how much the PC gaming landscape has changed over the past decade.

In 2017, £1,700 bought you an entire dream machine built around the best consumer graphics hardware money could buy. In 2026, that same sort of money barely gets you through the door for a flagship GPU alone. The economics are strange, but the performance gulf is telling: the RTX 5090 system is several times faster in many of the tests here, especially as resolutions rise and modern rendering technologies come into play.

However, the old Scan system isn't the write-off those numbers might suggest when you drill down. The GTX 1080 Ti and Core i7-7700K remain a remarkably capable pairing in the games they were designed around, with high-refresh-rate 1080p and 1440p gaming still very much within reach for those older titles. Even some newer titles remain playable with sensible settings, although the lack of dedicated ray-tracing hardware and modern AI-assisted upscaling means there are increasingly firm limits to what the system can do.

That perhaps says more about how well balanced the original machine was than anything else. The 1080 Ti earned its legendary reputation because it wasn't merely fast for its time, but rather remained relevant for years afterwards, and even now it can still provide a decent experience in the right games. There are still folks talking about how well it does today, which is a testament to its legacy.

Admittedly, the rest of the system has aged more unevenly, with the 16GB of DDR4 memory and tiny 250GB boot drive feeling particularly constrained in 2026, but there is still something satisfying about using a PC that once represented the absolute pinnacle of enthusiast gaming so far removed from the original situation.

The modern machine is undeniably better in almost every measurable sense. It's dramatically faster, more capable at 4K, and supported by technologies that simply didn't exist when the GTX 1080 Ti launched. Features such as DLSS, frame generation and hardware-accelerated ray tracing have changed what we expect from a high-end graphics card, while high-refresh-rate OLED displays, such as the one both systems have been hooked up to from Philips, give all that extra performance somewhere meaningful to go.

Still, there is a certain charm to the 2017 system in my book. It represents a point when a top-end gaming PC felt aspirational but not entirely unattainable — when spending £1,700 could buy the whole dream, rather than just the graphics card. The hardware may no longer be cutting-edge, but it hasn't become entirely obsolete either. If anything, testing it against a 2026 flagship proves just how exceptional the GTX 1080 Ti was, and how long a genuinely well-specced gaming PC can remain enjoyable.

The goalposts have moved enormously, but the old dream still has plenty of game left in it.
