Good news to all owners of this PC.
Got 2x 460GTX 1G MSI Cyclon in there and Nvidia control panel enabled SLI.
Stone Giant Benchmark up from 48 FPS 1x 460GTX in 1080p to
90 FPS 2x 460GTX in 1080p .
And thats missing the SLI Bridge.
It may not go up with it on, a MB with PCIe 2.0 but ill know in 10 days or so when i get it.
