Well if I do have to replace both I think I'm going to have to go Ati after this...
The only small consolation for me is that I can still use the machine for everything else aside from 3d apps. Not much of a consolation but I'll take what I can get at this point.
I also put an ati card in my old system (HD5750 from Sapphire). And I love it
In my new system i will put an Asus HD5870
