The Radeon HD 6950 in CrossFire is definitely the standout pairing in our test suite, only in the Nvidia-favouring DiRT 2 does the competing GTX 560 Ti have any say in things.
What's interesting about these latest benchmarks though is just how relevant the GTX 460 SLI setup still is. For £280-odd it's a pairing that happily competes on most counts with cards £100 more expensive. For a very good SLI setup the twin GTX 460s are mighty good value. To be honest you could probably get very close scores with the cheaper 768MB versions too.
The Radeon CrossFire HD 6950 setup though does still rule this test. It soundly beats the fastest single card out there, the GTX 580, on all counts and is only slightly more expensive. This also bodes well for the upcoming single-PCB, multi-GPU cards from the two main rivals.
The Radeon HD 6990 is likely to be a couple of down-clocked HD 6970s, with the GTX 590 reportedly being made up of two GTX 580s. That's likely to mean the Radeon card will be cheaper, with the GeForce the performer.
