ShockTherapy

My roomate has 7900GS and I have a x1950pro at home. Mine runs a little better but unless you get the right one, you might get the case consuming behemoth I got. Mine is Ati but I have seen other brands with the slim form. I would recommend the x1950 but make sure you get the slimform especially if you intend to make use of Pci slots and possibly crossfire.
