So I just bought a Gigabyte 790gx mobo and I have a XFX 9600gt currently. My new mobo supports 8x 8x pci-e 2.0 crossfire and I have been looking at the 48xx series for my next upgrade. I am always on a budget so I would like to use the 9600 as long as possible ( thinking of getting vga cooler and o.c. even more ) but with the prices of these cards and the reviews I am leaning heavy toward ATI. My questions are------ Which is the best X-fire 2 card setup for price/performance, and FUTURE-PROOFING? 4850, 4870, 512mb, 1gb, ? I was leaning towards a 4850 512 x2 setup because I could get both cards for 260 to 300 dollars and looking at the benches that's a heck of a deal. I am used to a Nvidia single gpu solution so I want to do this build right. I still have to upgrade my PSU for the build so I don't mind waiting but I want to obviously get as much use out of the new platform as I can. Thanks for the help.... later.
