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?
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.
