Hello all :) 

Ok, I am just wondering, is running two cards at x16/x4 any slower than x16/x16?

The reason I am wondering is that one time I read that cards can't currently utilize all of the available speed of an x16.

Thanks in advance!

Do x8 x8. The losses for x4 are much greater than x8

Is that possible with the ASUS M4A785TD-V EVO?

Significantly slower. In fact mixing slots like that you would end up with worse performance than using two 8x PCI-E 1.0 slots (which have the same bandwidth as 4x PCI-E 2.0 slots). Of course if you have a 16x and 4x PCI-E 1.0 slot the results are a little worse. Anyway, the crossfire drivers really don't like uneven PCI-E bandwidth so I wouldn't recommend it.

And you search you can find similar articles on other sites.

That board only has 1 x16 slot, meaning you will take a substantial perfomance hit if you decide to cross-fire.....
