Not that Nvidia wants people to test Quad SLI but it is more important to see that SLI contept might run on Intel's board after all. Nvidia is under a lot of pressure to enable its marchitecture on the Intel platform and I don't think it has much choice.
The TBreak chap took a Gigabyte 965P motherboard, stuck in a Conroe E6600 that works at 2.4GHz and managed to make two 7950 GX2 cards work together.
It's not just a SLI, it's SLI x SLI, as each card has two chips. And it works but its still unclear whether Intel and Nvidia will come to an agreement that officially allows Conroe chipsets to run SLI.
Take a look at the shots and the little experiment, it is all here.
