  1. Hi,

    For starters what's the budget of this build?

    I believe your CPU and motherboard aren't compatible. That's a socket 2011 CPU and a socket 1155 Motherboard. I'd go for an i5-3570k for the CPU, you won't notice much difference in gaming between that and an i7.

    Video-card is good, it should be able to handle all the games you mentioned at highest settings on a 1080p monitor.

    Why 32gb of memory?? No purely gaming machine needs more than 8gb.

    You really want bigger than a 64gb SSD. 128gb is the norm for gaming machines. Also that's quite an old model. Go for a Crucial m4 or a Samsung 840 Pro for much stronger performance.

    Not personally a fan of closed loop CPU coolers. I think a Noctua NH-D14 will beat the H100 in both price and performance.

    Something around the 600w mark by Corsair or Seasonic would be good (Antec are also solid). I like the Seasonic M12ii personally (620w version).

  2. -i7s are not for gaming, i5s perform the same
    -x79 chips dont work with a z77 board
    -fast ram is useless
    -tons of ram is useless for gaming
    -cheaper and faster hDDs avaliable
    -tiny SSD wont do
    -better 670s out there than the ftw. if you dont mind radeon, they perform better and come with free games
    -dont bother with cheap liquid coolers. get a heatsink or go full custom

    get this and you are good to go

    downgrade to a xfx 550w if you are not planning to run 2 video cards in the future
