Also, it's a dual head card with tv out. It was supposed to be about as good as you can get on a pci system with Aero, just doesn't preform. Works nice with the standard 2d classic GUI on Vista, and perfect on XP. As soon as you switch on Aero everything crawls. I don't get it. I have a power mac g3 with a rage 128 PCI running 10.4 and it's smooth.
