I am going to get another 5850 for my setup and what i noticed is that in crossfire mode my mobo only runs at dual 8x mode. Will decrease performance?
 
Solution
Yes, but not enough to saturate a PCI-e 2 x8 link. I own an old mobo and its PCI-e 1.1 x16 is like a PCI-e 2 x8 link, I was asking about viable upgrades and a veteran told me I shouldn't go above 5850.
