I wanted to buy a GTX 760 and later on end up getting a second GTX 760. I currently have an FX-6300 and was wondering if i would get any bottleneck when playing games. The other thing I thought of was to get one GTX 760 and instead of getting another GTX 760 get a FX-8350. And finally what kind power supply would i need for an fx 8350 and two gtx 760's. One card will run on a pcie 16x and the other on a pcie 8x
