Disagree: ATi's new drivers (5.1) are massively buggy, and Nvidia still leads by a mile and a half in Doom 3. ATi's optimisations have been to use brilinear filtering - basically lower image quality, better performance. Considering that Nvidia got labelled cheats for doing that (and now no longer do it) that's a bit rich from ATi, who've now lost moral high ground both in dual-slot coolers and image quality.
