So i want upgrade my dual core g3258 to something with more cores and that will last for a few years as a decent cpu. I have been looking at both the 4690k and the 4790k and also a few zenon's. i do a lot of multitasking while gaming. Ok here is my problem as it stands i can't overclock my cpu for some reason, my guess is memory or poor psu. or it could just be crappy wires in the home i live in. So there is my problem. please help if you can.
