Can You Run Nvidia Dual Graphics Without SLI?

The first SLI technology released into the mainstream was the 3Dfx Voodoo2 series back in 1998. While the semantics have changed from "Scan Line Interleave" (3Dfx) to "Scalable Link Interface" from Nvidia, the fundamentals are largely the same, involving disseminating graphics-intensive algorithms between multiple GPUs. This allows the integration of multiple cards into one system to take advantage of load balancing to increase frame rates. However, Nvidia's SLI usually comes at a small price premium, so we've tried to take a crack at an unapproved "GLI" solution from Epox to see if the numbers can match those churned out by SLI systems.
