While NVIDIA nearly got sued over their lack of Vista-ready drivers for their G80, ATI isn't exactly innocent. The Inquirer did a quick experiment to see if it was possible to configure a Vista workstation with an ATI FireGL graphics card.

To their surprise, it wasn't. This is because ATI does not have any FireGL drivers compatible with Windows Vista. And unlike NVIDIA, they do not even have beta drivers out. While most of the gaming community is more likely to use an NVIDIA G80 than an ATI FireGL, this is still a major problem for anyone relying on a FireGL based workstation. TechPowerUp
