No problems for me with Borderlands. The only issue I had was the grey textures that is fixed with the latest (9.12) drivers. No crashes for me.
The only problem I now have is Dragon Age's Anisotropic Filtering flushing on and off while playing. I don't know if it is ATI cards only that cause AF issues in Dragon Age.
I didnt know the grey textures were fixed with 9.12 Nice
The only problem i have with this game is (besides the grey textures already corrected) the performance. A GTX 280 can do as nearly much as my 5870s in Crossfire.
But ive heard bad things about The Saboteur.
