I recently got Borderlands. I figured that it should be a pretty easy game to run, but was sorely mistaken. With my 2 radeon 6950's, I usually pull around 40-50 fps. Now, this might not seem like a problem, as it's still playable, but it can get annoying when it dips down to the 30's, and I've become a bit spoiled with my system and would like a stable 60 fps. I've tried disabling one on crossfire, but to no avail. Any tweaks/ suggestions?
