I have this exact CPU sans a 3090 (I started with 2080 but upgraded due to local AI needs). 8700k is perfectly fine for todays workloads. CPUs have stagnated and also the amount of RAM in systems has too (Apple still macbook air defaults of 8 GB in 2025??????)
It wasn’t “workloads” being talked about, it was gaming performance, the one area in which there is an absolutely huge difference mainly on the GPU side. We are taking a difference of close too if not 100%.
And despite CPUs stagnating it’s absolutely still possible to be held back on a stronger GPU with an older CPU especially in areas such as 1% lows, stuttering etc.
