Not quite. 7970 in CF performs close or similar to 6990 CF.

I can tell you that running on 1920x1200 maxxed out with 4xAA on a 36MP server with 2 7970's makes the game crash. The VRAM is usage is crazy. It goes over 3GB of VRAM..

Turn HT on and overclock the 2600K if you haven't. It will make a difference in MP-64.
