considering hte card you listed is used mainly for CAD and similar programs you may have issues.
the gig is not your worry point, it is how the card uses other aspects to render the game.
you may need to tweek in game video settings to get results.
id start with dynamic lighting and background rendering....(forget the name right off, but the help box appears when you hover over it.)
Thanks for the advice...only problem is getting in game to do those tweaks. Even in safe mode, the game is encountering a fatal error with the video driver before I get in game or within 3 sec of actually getting in.
