ATI cannot make working video drivers

[OC Nub]

I currently have 2x3870's, 2x4850's 3x4890's 2x5870's and thats just a small %age of the ATI cards I have had over the years. I always thought most people that complained about ATI drivers were either being extremely picky and looking for something to about, or they were closet NVidia Fanboy's just looking to bash ATI, until I started trying to run BC2 with crossfire 5870's. No matter what I try I either take a huge hit in FPS or I get great FPS but the game closes about every other game at best. I am faaaaar from being an NVidia fan, but this issue has pissed me off. I ordered 2 Palit GTX460's and they run BC2 great in SLI, the FPS arent as high as with the 5870's (when it actually worked) but the game runs smooth on max settings and 0 crashes.
