AMD has two new drivers today; the 12.6 WHQL and the 12.7 beta drivers, you can find the full changelog and download links at this page.
Both drivers resolve the following issues:
Using AMD Radeon™ HD 7900 and AMD Radeon™ HD 7800 Series in TriFire or QuadFire configurations with AMD Eyefinity will no longer result in a BSOD when launching a DirectX® application.
Multi-display configurations will no longer BSOD at the desktop on AMD Radeon™ HD 7000 Series GPUs.
Additional fixes for AMD Radeon™ HD 7900, AMD Radeon™ HD 7800, and AMD Radeon™ HD 7700 Series GPUs hanging the system upon entering sleep. Some occurrences of this issue may be related to an outdated motherboard BIOS, however. Please ensure that your motherboard BIOS is up to date.
