Just because nVidia is promoted in some of the games you play doesn't mean it performs better in them. Look at all the benchmarks. Even Crysis, which nVidia sponsored, is ran better on the new ATI cards.
But to answer your question, INNO3D is a decent manufacturer. If you really have to get a GTX 285, I'd stick with XFX, eVGA, and BFG for their support services and warranty.
