So I just built the system in my sig. Once I got Windows 7 64bit installed, I installed all the windows updates and the MB drivers. Everything seemed to be running smoothly with no drivers installed for my ASUS EAH6870 DirectCU. I downloaded the latest drivers from the ASUS site, installed and restarted and the Windows login screen is completely jacked up looking. It's light blue but I can't see the password line or shutdown button unless I mouse over that spot and even then it's weird looking. I've also tried the latest drivers from the AMD site and tried only installing the driver without the rest of the Catalyst software. I also tried the Vista drivers from the CD that came with the card. All result in the same problem.
Here is a picture of the Windows login screen with drivers installed: https://plus.google.com/101582118245591966843/posts/6GdYC3cqwrh
