I would buy the i7-3770k and the Z77 motherboard combo or the i7-4770k and the Z87 combo, whichever you get a better deal on. Get the all-in-one liquid cooler kit for the CPU and you'll be glad you did! I have the Intel DZ77GA-70k motherboard, but if I were to do it again, I'd try the ASUS Sabertooth motherboard... I'm not at all unhappy with the Intel board, though...
Seriously that money christ on a bike you could duild a BEAST...
