New to forums. Just purchased a first gen(2006) mac pro off ebay and found out it had a x1900 for a video card, I have a 8800gt in my old comp(hackintosh) but tried removing the ati card and installing 8800gt and no luck. Could anyone reccomend me a video card that would work maybe out of the box and that isnt too expensive, really wanna spend 100$-150$ max.
