For video yes, but they're complete shyte for everything else. Soundstorm has absolutely no nvidia driver for it at all. Neither does their network adapter. Thank god one of the onboard NICs on mine runs off of a 3com chip or else I'd be screwed.
Wanna know what sound driver you have to use to get any kind of audio with nforce2? snd-intel8x0. No hardware mixing (one sound at a time), no DD.
