We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: Intel, ASRock, Kingston, Mittoni, Noctua and Corsair.

The setups we're looking at today are almost identical to when we looked at the GTX 580 1536MB in SLI. The only difference here is we've removed the GTX 570 GLH Edition from Gainward.

What's here includes the GTX 580 1536MB in SLI at stock speeds, MSI GTX 580 by itself and the HD 6970, HD 6950, HD 6870 and HD 6850 all in Crossfire.

Let's get started!
