hey,
would 2 Nvidia 8400 GS's, SLI, be better than one 9600 GT? I'm down to choosing between two computers now, this will probably be the deciding factor for it.

ActionGrant is correct on this one - you'll be MUCH happier with the 9600GT. As a general rule, you should always choose the best, single card over two, lower-end cards. As ActionGrant said - this means you'll get the best performance possible...especially since not all games utilize SLI mode.
