Have a google on that card with maya.

The gforce cards are generally not qualified to run wth maya, though most of them do, with very little problems, you might need to cange some settings etc. On the 8000 series I remember a few people having issues with them, have a look over in the maya section on CG talk, you mght need ot search it though.

You'd get the same problem on the macbooks (pro's too) as non of them come with a 100% card, think it even outlines the problems with them on Autodesks site
