amd phenom II x4 955 at 4.0ghz
asus m4a79xtd
4gb ddr3 1600
bfg 550w psu
hd 5850 1gb


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?

Yor psu is arguably too weak for xfire...and your going to bottleneck it with the dual 8x mode. Its time for an upgrade

A little bit. but not by much maybe like 1-2%, only the top of the line cards like a 5870 could saturate the x8 link and need the x16.

i know that my psu is weak, i was just asking about the 8x link. I already orderd my pc power and cooling 860w psu. And another question. Isnt the 5850 a top of the line card?

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.
