I've recently got UT3 and Crysis for my Birthday, amazing games. But I've found they sometimes slow down when everything goes boom, or if i collapse a building or something. I have a Geforce 8800 GTX and a 2.4 Ghz AMD dual core, and 2 gigs of RAM. I'm wondering if the solution to this is to buy a PhysX card, and with Christmas coming up I have an opportunity to get one.
I'm just wondering if anyone has one and how good they actually are. Any advice would be great.
