Yes, I am running Windows 7 on my iMac through Boot Camp (there are some Windows only apps I need for my business and I didn't like virtualization). First, it's fast as hell.
The one thing I'm not liking is that the sound sounds horrible. It's just "off" -- very tinny is the best I could describe it. I installed the realtek driver off of the Apple disc (beforehand there was no sound at all).
Is there a "better" or "different" driver I should be using?
