They will perform about the same (the 7900GT might be a little bit faster), but the 7900GT will be cheaper and use less power. Plus, you'll save money on the motherboard, as non-SLI mobos are cheaper.
Hi! I'm not really familiar with the capabilities of these new graphics cards, and I'm just wondering what would be better, two 7600GT graphics cards or one 7900GT? Thanks!
