I think the main question of this thread has already been answered, but I was wondering...
Since not all motherboards with 2 PCI-E slots, really offer x16.
I have the Gigabyte GA-EP45-UD3P, which has 2 PCI-E slots, which supports CrossFireX, but from what I understood, each PCI-E slot individually can run at x16 speed, but when 2 video cards are crossfired, than they'll work (in my case) in x8 speed. It that true? (I guess the answer is YES).
If so, anyone knows what is the performance drop of using two high-end ATI Video Cards in CrossFireX x8 compared to running the same 2 cards in full x16 speed?
