I plan on purchasing a few 5850s and putting them in Crossfire.
Will I see performance degradation if the cards are in PCI-e 3.0 x8? Would x4 work?
5850s came out something like a year before the 3.0 standard, so I can't imagine they're bottlenecked by 2.0 speeds which are essentially 3.0 x8 speeds, I believe, but I would very much appreciate if someone has experimental data on this.
And while you're here... anyone have a suggestion on a <$100 AM2+/AM3 mobo to purchase which would support two 5850s and preferably give them some room to breathe? I'm considering the ASRock 870 EXTREME3
@ $90 shipped.
