ZOMG My 2900XT has been sitting in the closet gathering rust and dust for almost 2 years! Meanwhile I have been living on the nVidia blob and a 8800Ultra happily ever after. Everyday I read the news that R600/R700 3D is not coming up makes me feel happier because I did the right thing and tossed it not too late.
Guess what, I'm actually thinking about donating my 2900XT to some X.Org developer. Who wants one?! Buy the way you need at least a 550W PSU, tons of 12V Amps to power it up.
