I have dell 990 optiplex currently with stock everything except for a gtx 960 for gaming that does extremly well. Cpu is the. I5 2500k. In a couple months or even sooner i hope to upgrade my cpu to a faster i5 or i7. Just wanted to know if theres actually any cpu faster than the 17 2600k thay will work in these things. If not ill jist leave it how it is for a year until i build a pc from scratch.
