Main rig here is still a 2500k
Saw a youtube vid showing how for most people outside of doing editing/streaming or rendering etc You are all good. All just to do with throughput, memory/mobo and gaming graphics card still the big one.
My eldest brother still has one. Trying to run modern games in 4K resolution might break it a bit.
1440p it still did elite dangerous on full throttle (decent GPU)
But I don't run much game wise on it, tbh my main resolution for gaming atm is 240p
