Why would that concern you unless you are working on the cutting edge and the very limits of that hardware?
The current generation is insanely fast. I am planning to get a gaming PC for my wife and a mix of gaming + workstation PC for me (or maybe just base it off of the Ryzen 9950x3D and call it a day). We plan to hold on to them for 10 years.
I don't care if anything 6x faster comes out. For what I need the current generation is even an overkill.
I'd even go as far as to say that it would be quite OK if that's the very last generation and no further hardware development ever happens.
I am on the edge of current available hardware and do feel the desire to upgrade. As stated before, I am unhappy with the current maximum when combing frame generation, resolution, and graphics quality.
My dream spec is UE5 at 120hz on an 8k oled. I think that sounds like a super sick experience I would buy tens of thousands of dollars of hardware for.
Will we continue to see steady improvement in top quality CPU/GPUs? Would they even bother releasing consumer versions of ram faster than DDR5?
