I would go with the ATI also. But this may sound like a stupid question but you do have an open AGP slot right? Brownish slot in the middle right over the white PCI slots. The only reason I'm bringing it up is that you said you have an intergrated video card and it may not have an open AGP. Not all intergrated boards have an open AGP slot. You probably already checked but I dont want to see you waste your money on something you cant use.
