Best graphics drivers to use for ATI Radeon 6800?

view story

http://forums.fedoraforum.org – Hi, I've installed the FGLRX drivers using a guide from here and am able to now play quake live, yay! But now I'm trying to run Dota 2 using wine which shouldnt be a problem but the FGLRX drivers don't support something todo with RGB OpenGL that wine uses. The original drivers fedora installed wouldnt let me play quake live (Sorry I dont know what they were) What open source drivers should I use for a Radeon 6800? If anyone has a link to a guide aswell that would be great. First time I tried to installed FGLRX i couldnt get the desktop to boot and had to reinstall Fedora. Thanks. (HowTos)
