Thats an ageing card now, anything from an X1950Pro could run this game maxed and they going cheap now hell you can get 2900XT's for like 80 quid now and they will run it on high so really you dont need an expensive card to max it out.
Yeah, I know what you're saying but when I'm helping out a casual gamer they don't really have £80 to spend on a graphics card.
