ATI rolled out a unified driver for Microsoft Windows Vista and Windows 7 Beta last week, intimating Vista-matching performance for the new operating system whose release candidate is scheduled for the end of May 2009.
Windows 7 uses an updated driver model, WDDM v1.1, and ATI's confident that its drivers are up to scratch right now. We took a look at Vista and 7 performance on an ultra-high-end Radeon HD 4870 X2 2GB card, finding that, in our gaming suite at least, ATI's claims were borne true.

However, these £300-plus cards are few and far between, so, today, we take another look at Vista vs. 7 performance, but with a Radeon HD 4870 1GB vs. GeForce GTX 260 896MB - with both cards now shipping at around £175.
