It used to be that if you wanted to make use of NVIDIA’s multi-GPU SLI solution, you were stuck having to buy a board that was fitted with an nForce chipset. X58 motherboards for Intel’s Core i7 CPU changes that.
This is an interesting move for both Intel and NVIDIA. What NVIDIA has done in effect is certify SLI on X58 motherboards despite there being no nForce chipset in sight.
Did NVIDIA have a choice? No, not really, not if it wanted hardcore enthusiasts to have access to dual/triple/quad solutions on what will be the fastest CPUs going. Intel gets the best of both worlds and is able to offer enthusiasts both NVIDIA’s SLI and ATI’s Crossfire multi-GPU solutions for it’s next-gen CPUs.
