Hello everyone! So My dad picked up an old dell optiplex 755 pc a while back and its did it's part, I threw in my GT 430 Low profile in for a little unfff. Anyway we need more power, at lest my parents do, so I did some research and found that the intel core 2 quad Q6600 has the same socket has the aging Pentum E2160. So could i buy the $40 cpu and have it work? or would there be a compatibility issues? if so what would could/should i buy instead?
