Ok, trying to help my brother configure a Dell (hold the snickering, please). He does want to do some gaming with it, which leaves the Dimension 8400 as pretty much the only option. I'm telling him to skip the X300, leaving 2 choices for a video card; either 128MB X800 SE (a neutered OEM X800, from my understanding), or a 256 MB 6800. I don't know what Dell uses for the 6800 (plain vanilla, from what I can tell; they also offer a 6800 GTO, but that's a budget-buster). What would you choose from these options?
