The GeForce 8800GTS 320MB SLI combo really perform well in 3DMark06. Here we can really see the difference between the single GeForce 8800GTX (the MSI NX8800GTX-T2D768E videocard) and dual 8800GTS in SLI. The SLI setup is the only one to break the 10,000 point mark in the 'Overall' portion of this test.
