I was wondering whether I should go with an ati x1950 pro 256 or 512 mb card or xfx's nvida 7950gt 512 mb card. I am planning to eventually get a 8800gts 320 mb card and if it matters I am getting an sli supported motherboard for the computer I am building so if I wanted to I could eventually go sli with another 7950gt ofcourse I would have to upgrade to better power supply then I'd imagine (my case is coming with a 500 wat psu). Here a link to the xfx card.
