Is Crossfire worth it on this MotherBoard? MSI Neo2-FR P35

My current motherboard is an MSI P35 Neo2-FR, which is running a Q6600@3Ghz and 4GB DDR2. I was considering running two cards in Crossfire perhaps two ATI 5770s. However, my Motherboard documentation states that 1 of the PCI-e slots runs at the full 16x, but the other at a lower 4x. If I was running two of these cards, am I going to see a significant bottleneck because of the 4x PCI-e slot? Is this set-up actually worth?

Thankyou for any help :)

  1. Are these PCI-E slots 2.0? If so, you may notice a slight (1-2FPS) decrease in performance, but nothing major.
  2. It says they are 1.0
  3. Then stick with a single HD5850.
  4. ok, Thanks
  5. The P35 is not a crossfire chipset, that would be the X38.

    Actually, it technically supports it, although it wouldn't be preferable.

    Check under the "Slots" section.

    That's a bit of a surprise because my P35 board does not support Crossfire. Thanks for the edumactation mate.
  8. MouseMonkey was proven wrong.

    We should record this moment in the TSH history.

    TSH?, what's that?, and at what point have I said that I was never wrong? or are you just sore that you don't know too much about the way that cards work in SLi? [:mousemonkey]

    That Abit board only has one PCI-e x16 slot, so Abit probably skipped on the CrossfireX certification.

    I thought it was really weird when I saw my Asus 750i SLi board had been used in high-end OEM rigs with dual 4850's in CFx. O.O

    I know mine does not but there are five others in the same family one of which does have two PCIe slots but no Xfire support as far as I'm aware.

    According to this review, along with a bunch of other ones found whilst Googling (damn, that always sounds so dirty) the IP35 PRO has CrossFirex support. From what I read, at first, the P35's were awaiting ratification for CrossFireX support, and got it after the boards were released. Then again, this IS the internet we're talking about. ;)
