For physx 8800GT wont bottleneck - remember - you are using it for physx, not rendering the picture. And nobody use one more 480 for PhysX only. You wont be able to gain most from your system. Anyone with common sense will put them in SLi only.Q2M100 wrote:If you ever play a PhysX enabled game, the 8800GT will severely bottleneck your system. Two 480s will be able to render the graphics and process the PhysX much faster than if the 8800GT did the PhysX. I couldn't find the link, but there is an article where they test different GPUs with and without different dedicated PhysX cards.
But anyway - why people are so worried about it, I can't get it. If you have 480 or smt then why you worry??? The card is capable do a a lot by it self.
