The Nvidia GeForce RTX 5090 is now out, having launched on January 30... and very swiftly sold out. If you were lucky enough to get one - congratulations! If you missed out, make sure you check our where to buy the Nvidia RTX 5090 guide, as we'll continue to update it as stock comes in.

Even if you're not planning to get an RTX 5090 any time soon (that $1,999 / £1,939 / AU$4,039 starting price is no joke, after all), you're probably keen to see if Nvidia's new flagship gaming GPU can deliver on the 8K promises Team Green has made leading up to its launch. It can also give us a clue about what kind of performance more affordable RTX 50-series GPUs will be capable of.

As I mentioned in my initial 8K tests of the RTX 5090, early signs are very promising for the 5090 when it comes to 8K performance, mainly thanks to DLSS 4. That is Nvidia's new and improved upscaling technology, which can help games hit higher frame rates while minimizing the impact on graphic quality. DLSS 4, alongside Multi Frame Generation, really feels like it will be the tech to watch this generation and has the potential to make gaming at 8K a reality.

Best of all, it's not exclusive to the 5090, so all RTX 50-series cards will get it. And, while the more affordable end of the series will likely still struggle at 8K, it has exciting implications for people gaming at 4K - you may not need to spend a fortune on a premium GPU.

The launch of the RTX 5090 also gave me the opportunity to overhaul our 8K test rig, so I've built a new one from scratch with some of the latest components to ensure there are no bottlenecks and to get the most out of the RTX 5090's potential.

For an extra challenge, I built this super-powerful PC inside a small form factor chassis - and I'll be detailing my experience building the compact 8K powerhouse in an upcoming article.

Now that the PC is built, I wanted to give it a run for its money by seeing how well (or not) it could run Assassin's Creed Shadows,which has just been released after several delays, at the ultra-demanding 8K resolution. Could this be the start of a brand new generation of gaming?
