So I'm having "slight" lag with my AMD FX 8120 and overclocking is not agreeing with me. I'm looking into buying something better and since people said I should have gotten a Sandy Bridge CPU I think a Haswell CPU would be a nice upgrade. I wanted a i5 like a 2500k or 3570k except the Haswell version. Any ideas on when this would come out and would it be worth getting?
