I was going 2 build a pc when I could get enough money, but while I was saving up all these new thing started to pop up like nvidia 770,780 and now the new haswell CPUs. Im thinking about changing to the new haswell cpus but im concerned about the motherboard, the asrock z77 extreme 6 cost $145 for me but the new asrock z87 extreme6 costs $237, the asrock z87 PRO4 costs $149, I'm confused about what motherboard I should get, is the new z87 extreme 6 same as the z77 but just costs more or does it perform better as well, or does the PRO4 have the same performance as the z77 extreme 6. I don't know what I should do, just stay with my current build or get the new stuff while I'm at it.
