FUD Zilla claims NVIDIA is developing an improved version of SLI, the rumour mill says SLI 2 will use two graphics cards for graphics and another one for physics:
SLI 2 = SLI + PhysX and this cannot be more simplified. We don’t know when will this launch but the new driver that supports PhysX is finally out so any board with three PCI express slots should be able to cope with this new SLI 2.
This will look good on new boxes but as you can see it’s not anything spectacular. We will keep our eyes on it when will this launches.
