My choice of processor will be Sandy Bridge (i5 2500K). So according to what you guys have said, I should only get the gen3 version if I have a ivy bridge which I won't.
Also, are there any motherboards that I can get a better deal on? I will be having i5 2500k with a radeon 5870 GPU.
extreme is good enough but if you want more powerful then look at asus p8z68 vpro gen3
