Actually, 2 768mb 9600 GSO's (basically 8800GTS's). And 35fps @ 16:10 @ high setting with 1 $65 card is pretty **** good if you ask me. Considering that it only has a 192 bit interface. These 9600's OC very well, easily 30%, could possibly get more if I volt modded. Dollar for dollar it has more performance than most if not all available cards.
Im building 2 more rigs in the very near future, 1 crossfire and another nvidia machine. When I step my cards up to the 260's Ill run 1 260 in each machine, new build and current rig. But just for kicks and giggles, Ill sli them on my current rig and see what kind of results I get.
As for the xfire rig, I might go with comething cheaper for the time being 3870's perhaps, then get 4870's when the 5xxx series come out, basically when the price is right
