"NVIDIA's upcoming MCP7A motherboard Intel chipset is expected to launch this coming April along with the 45nm Intel Core 2 Duo E8300 and the 65nm Core 2 Quad price drops.
The MCP7A line will support a 1333 MHz front-side bus and 20 PCIe 2.0 lanes in a possible 16x1 + 4x1 setup. This would allow a single GPU expansion card to be used in conjunction with the GPUs in seven of these chipsets for a Hybrid SLI setup. The only two SLI boards, the MCP7A-SLI and MCP7A-GL, will feature 2 x8 PCIe 2.0 slots for dual expansion card capabilities."
Hopefully this will be better than the 790i.
