I'll be using my old GPU as a PPU (link
) and replacing the 560ti GPU with a uber GPU in about a year when they bring out the 7 series. PPU's don't need as much bandwidth as a GPU especially since it's a very old card. I will for sure download the manual n have a read and see what it's capable of. While I'm at it you reckon a 750watt PSU will be enough or maybe need to push to a 850? I reckon 750 should be enough.
