I have seen the Xfire thread, its got my pretty excited as my board can support Xfire, albeit at a limited 4x Speed slot on the second card.
Anyways, I've just rebuilt my system software, changed my overclocks a little upwards after playing with the heat dump of my W/c,and got the following results:

PCI-Ex 4x Test Results:

2001 - 25502 - 7.14% loss
2003 - 13635 - 12.05% loss
2005 - 7738 - 13.87% loss
2006 - 4122 - 9.92% loss
These are interesting results because despite only having 1/3rd the bandwidth on the slot it seems a broad '10%' loss can be applied to the video cards output.
I think I might run through these tests again, but with an Overclock on the PCI-Ex bus (if I can get it stable) of 110Mhz, a 10% overclock.
