Thats true Mat, I think its horses for courses, like I said my one of my PC's at uni has the X1300 in and its horrible (you can still work in maya but its a bit flickerey and the textures dont really show up well, and sometimes the viewports lock up) on the otherhand the dual X1900's that my other uni PC has is perfect, no probs at all.
Ive got a Gforce 4000 inn my home desktop and thats fine with maya, so is the Gforce 7900 GTX, although I hear on other forums that the 8000 series Gforces have a few issues.....????
Its a confusing choice and with the gaming cards being a lot cheaper than the Qualified worksations cards with similar specs, its a bit of suck it and see, since you'll have no probs with a qualified card, but its gonna cost ya, or you might have a problem with a gaming card but its cheaper and you can work round it, or it might be perfect!
