There is a good chance I will pick up a second HD5850 in the future for Crossfire. Will the x4 lane bottleneck the Crossfire?
I've read the "PCI Express And CrossFire Scaling: Is P55 Good Enough?" article that pitches the P55 (x16+x4) against the X58 (x16+x16) with two HD5870 cards. Based on the article there appears to be very little difference for the two-card Xfire configuration so I am assuming my lesser HD5850s should see even less of an impact. Is this assumption correct and the motherboard I am considering should not bottleneck?
