if you want something faster but is in the same price range look at the r7 265 / hd 7850 2gb version / hd 7870 / r9 270 / gtx 650 ti boost 2gb version
if you really would go for the gtx 750 ti get the palit stormx oc 2gb version it is slightly overclocked and does not need a 6 pin power connector unlike the 750 ti FTW version or the direct cu II.
