that's if you're agp, if you're pci express just go for anything in the nvidia 7 or 8 series without a fan on.
The only reason I'd avoid the 6 series right now is because it's pretty much going obsolete. The last 6 series card I had before I upgraded to the series 7 (had it from about 2002) couldn't play a number of video demos and such because it didn't support all the routines that the programs called. Yeah, it's unlikely this would be an issue for someone just doing audio but, given there is the chance that the machine might be used for some game or other visually demanding app, I don't see any reason to not go with a series 7.
