K hi hihihiiiii im buying an ATI radeon 9800 pro and right now i have a nvidia geforce fx 5200 installed. if i install the ati...will it work? if i dontload/install the drivers and such? or do i have to uninstall the nvidia ones first so my computer doesnt go crrrazzziee? i herd that you should reformat before you install a new video card, but i just reformatted and got everything back to normal so i dont want to!
