Pros: I posted before about how well this card works under workstation loads. Now I am going to tell you how well it work while gaming. WOW! I took this card home from work for a LAN party I was hosting. It blew everything compleatly away. I have never seen or used an 8800 Ultra, but I am sure this this can top one, possibly 2. I was running Crysis on high, everything as high as it can go, not just water or objects, every setting on VERY HIGH! Anti autoleasing as high as it would go (X8). The game looked wonderful, no lag, no frezing, no nothing. The rest of the system was not even that great. Core 2 @ 2.2 GHz and 2 GB of RAM and some old IDE drive I had laying around. If you are insain and have lots of extra money laying around, get 2 in SLI and then you have something to brag about.
Cons: Obviously the price, but like I just said, this will run around a 8800 Ultra, since the guys that own them say that they can not run Crysis on the highest settings, and I can.
Other Thoughts: I would imagin the Quadro FV 5600 would easily top this card, or the FX 4600 X2 I guess, but this will play the most demanding game on the face of the earth (at time of post) and will run several GB 3D solidworks assemblies at work, I am not sure what else needs to be done that can not with 1 or 2 of these cards.
