Ah, that makes sense. Tbh, I didn't even realise it was a new architecture. Haven't been in the game for 5+ years. I saved a fair few quid not getting the K version of the i5 because while I like the idea of OC'ing I'm not really doing much that I'd see any real improvement from it. (also anything I could buy nowadays is going to be a marked improvement on my E4600 I had previously)
