For context I built my rig 1.5 years ago. It currently has 7800XT and is running smoothly.

But with AMD intentionally not giving FSR4 to RDNA3 users and talks that UDNA will bring FSR that can't be used on RDNA4..... I'm just sour on AMD. I can't buy stuff that becomes obsolete tomorrow.

I was browsing the second market and found an amazing deal on an RTX 4090.

Are Nvidia drivers on Linux any better today? And I'm not talking about the setup, that's the least of my worries.

How is the performance impact? RTX 4090 should give me at least a 50% performance boost in raster, and let's not even talk about RT

But that's pointless if translating DX12 via Proton and RT inefficiencies cost me 20-30%

I was browsing a second hand marketplace casually for PC parts.

I came across a listing for a Ryzen 9900x for quite cheap, more or less equal to a 9600x MSRP.

I have a 9600x + 7800xt system, and I mostly play AAA games at very high settings (without RT).

Will I see any benefit from this upgrade? Let's say my sample games are Ghosts of Tsushima, Cyberpunk, RDR2, Control and Black Myth Wukong....
