I created a new primary partition on my hard drive and installed the Windows 7 Beta. Microsoft Update Catalog ( http://catalog.update.microsof.....%20drivers ) had a client driver for my AGP Radeon 3650 but not for my sound and ethernet. I searched the net for 3 or 4 hours trying to come up with either vista or windows 7 drivers for them and found nothing. As a last resort I tried the XP drivers anyways. They worked wonderfully!!!
The moral of the story is that Microsoft should let users know that in many cases the XP drivers for your hardware will work just fine on Windows 7. Next time, if I can't find the driver I need within 5 minutes (cuz I usually can), I'll just use the XP driver.
By the way, I'm running Windows 7 Beta on a single core P4 3.2GHz with only 1.5GB of RAM and it's running just as smooth as silk. As smooth as or better than a fresh XP installation. = )
