Will it make a big difference in gaming even if I got the 7970. I suck with patience but if the 3570k is going to wow me compared to the non k ill force myself to wait and game on my yawn.... ps3
Will it make a difference today... tomorrow or even 3 months. No it won't. It'll game just fine.
Give it two years when you are going to need that OC ability. Thats when you'll be kicking yourself in the face for not getting the K version. As others have said, patience is a virtue. Send it back get the right Chip. Im surprised thou that a combo deal would come with a z77 and a 3570 non k version.
