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?

  1. Yor psu is arguably too weak for xfire...and your going to bottleneck it with the dual 8x mode. Its time for an upgrade
  2. 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.
  3. 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?
  4. Best answer
    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.
  5. alright thanks. @ jamesyboy. I really dont think its time for an upgrade so i have no clue what your talking about.
