I am facing a similar choice and I think I'm going with 560 TI.....I'm getting 560 ti around $25 cheaper than 750 and $50 cheaper than 750 TI....750's have memory bandwidth of 128 bits and only advantage of 750 seems to be less power consumption and newer technology and I don't think there have been any unique features developed in Maxwell cards other than newer directx and opengl which aren't implemented in most current games...The Power consumption of 560 ti is however around 3 times higher than that of 750 ti so the difference in that aspect is massive
