Guess what? NVIDIA has come up with a new feature called SLI Physics! Join us as we find out what SLI Physics is all about! Link : NVIDIA SLI Physics Technology Report!
hmm.. problem is: the work that nvidia plans on taking over to one of the graphic chips in the system, is exactly the work programmers try to put on the 2nd cpu core. so..... yeah..... we will see, but i guess that using the second ore 3rd cpu core for physics etc will be more accepted than having to buy an additional gpu.
Hehe.. Naturally, NVIDIA is trying to sell more GPUs. If you want to offload the physics work to the second GPU, then you will need to buy a second graphics card. Hehe...
