Motherboards published a review of the XFX NVIDIA nForce 750a SLI Motherboard. This motherboard is available for about $150.
Quote from the review: "Making it targeted for the mid-range market and not the enthusiast motherboard market another board in the $200-300 range would be in. The board has support for SLI after setting jumpers and enabling it in the BIOS with two NVIDIA video cards of the same type. The integrated graphics is a bonus that has several benefits over not including one. HybridPower is especially beneficial in this day and age where everyone is trying to save the environment and make the move to a greener PC world."
