I've seen pictures of this in action but have yet to hear any word of actual benchmarks and can't seem to find anything on the usual forums. Have any of you seen any benchmarks on performance scalability with quad crossfire?
I'd love to see a 4x4 setup, water cooling each of the 3870's when waterblocks for them become available. Then we'll see if the new AMD OverDrive is worth the pilgrimage...
