Actually I think all 3 need upgrade. New card will help alot with the other games I have, but a new case will be good for the components to breath. CPU temps still running hotter than I would have liked with the Arctic Freeze cooler. Right now at 50c idle.
I'll post more details in the PC upgrade thread.
Sticking with cards, here is something thats been in my mind. If I do get this card, I'll have 2 8800GS. If I connect them both in Slot 2 and 3, enable SLI and make them both run PhysX. Possible?
