You can try to run 470 alone. Because strangely enough mine 480 runs faster when alone. Having 480 and Quadro 3800 , running Hackintosh. No Power kext. H264 (canon5d) around 12-15 nodes blur100 – 25fps. when together its always slower 10 nodes 23-24 fps. 6core 24gigs ram. Try also to change pci lanes , it changes slitly for me.
