First PC build under $1700

im wanting to build a new PC i've picked out some parts

what video card should i use?(i will be able to buy a 2nd of the choice in Q4)

what should i change?

should i wait for steamroller?

Sorry, I'm a bit busy right now, but I'd look into a 3770k, Gigabyte UD5 Z77, with a Phanteks PH-TC14PE, twin MSI 7950s in CF, a 500GB Samsung 840, Lepa G650 or Corsair AX750, 16GB (2x8GB) of G.SKILL Sniper 1866mHz CL9, all in an R4. In the middle of a LAN party, so I can't dedicate too much time to it, but I'm sure someone else will come along.

hey thanks for the input, it's much appreciated
