What exactly are you asking? Also, your sig only reads "Asus Z68" for the motherboard.

PCI-E 2.0 x8/x8 should not bottleneck two 290s in crossfire. I believe the performance loss is unnoticeable in games.

 From what I understand.. the GPU will not run full speed, as the PCI-E power savings features do not allow full clocks on Gen2 link speed. Someone that has a Gen3 GPU on a non-Gen3 mobo should chime in and confirm though...

If that is the case, I guess I will sell my second r9 290
