My processor is AMD FX-8120 8 core processor. I currently have a GM760-e51 mother board (picture below) my OS is windows 8, and my graphics card right now is an ATI Radeon 3000 (An IGP unit) meaning that all my PCI slots are unused, I have two PCI slots and 1 PCI express 2.0 x16 unused. My power supply is 480 watts, would prefer a graphics card that uses 190 or less at its peak. My price range is 160 or less ( though if its like 10 dollars above wouldn't mind checking the graphics card out). I would like the power usage of it to be less than 180 watts. My current possible options right now (and if you notice any compatibility problems please notify me) Geforce GTX 750 (Ti if I feel like its worth it) or ati hd 7750. (If you can compare these or add another one that is really competent to this ones within my price range it would be really appreciated).   Extra question I know the answer is most likely no but is it possible to crossfire my current igp ati radeon 3000 with any of this?    

I've always enjoyed Sapphire cards, and though there are no R9s in your price range, I don't think you could go wrong with this card. It also comes with two games, so why not?
