I got an incredibly deal on a pc containing a i3 2120, and I want to upgrade it. Should I put a i7 2600 in it (for like 65$) or a i5 2550k (for like 50$) and pair it with a 1060 6gb? Or should I do something completly different ? I’ve got a MSI B75(MA-p45 I think) motherboard btw. I heard something about it having a program that allowed it to overclock is that true?
