i cant seem to tell ive had any issues running apps, except some DX games, but they can be run in opengl. like wow warcraft 3, and to be honest, starcraft broodwar goes better on 2900 xt than 8800 GTS/GTX, which kind of suprised me.
well, you all might say, starcraft doesnt lagg on my whatever kind of videocard, but it doesnt lagg, till like 5 minutes in the game, the game start to become active and all that. like while playing with 200+ actions per minute, pro gaming.
well. i got some annoying bugs in like gnome, while using my workspace, thats the issue for ati users primarily i guess, for hd users probaly.
I think ati have gotten this driver nearly perfect for the HD series, just to give the same support all the way down to x700.
But with 64 bit fglrx gnome xorg and all that. it still means that we got a bottle neck >_< the GL! so i'd be expecting very simular results, i dont know, lets throw it in the party of benchmark, and see what happens
