I sent a ticket in for this earlier today, but figured I would post here for community feedback. I made a video showing one of the games that I have issues with; Crysis 2. I posted the 1 minute video up on youtube. The video shows some odd screen behavior and it's not the kind typically reported by others. Nor do I seem to find any solutions to this problem. Since I've had similar problems with the 5770's in this same mobo, I'm starting to wonder if I'm having a mobo problem here.

I'm using the i7 3770k, which utilizes pcie 3.0 architecture. This is rather new architecture and I'm unsure if I'm suffering from a common issue with this configuration or I may have a defective unit. Here's a link to the video:

Other issue:

Saints Row 3 wont load correctly of either a save game or a new game when vsync is enabled on a crossfirex configuration. If I turn off vsync, I can run the game fine. If I turn off crossfirex, I can run the game fine with vsync. Rather odd behavior.

Mass Effect 2 also has strange graphic issues where dialog options would "flicker" in crossfirex. There would be screen flickers similar to what is observed in the Crysis 2 video I uploaded to youtube. 

This is more than just microstuttering as the game isn't really "stuttering" as it's just glitching out like there's a loose connection or something. But I've had this issue with 5770s too so again, I'm wondering if there's an issue with the z77 configuration. Or a possible defect in my mobo... or component on my mobo.

Here are my dxdiag specs:
