I have a new GA-E7AUM-DS2H that I am using in a Windows 7 RC1 HTPC.  I am pretty happy with the board but it is not with out it's faults.  I continue to have issues with sleep, going to, and waking up from...but the bigger issue is the terrible performance of the Nividia IGP in Windows 7 Media Center.  Menu Scrolling is painfully slow.  Hardware decoding of h.264 is fantastic.  I am using the latest Nvidia 186 drivers.  I have Dell notebook with the same 9400 Graphics chipset and menu scrolling in 7MC is fine.  What's the problem?
I had a 3 year mobo with an Nividia 8600GT that blows this chipset out of the water when it comes to 7MC menu scrolling.
