1. Yep, either on day one or day two. Only issue I had was the initial problem with Nvidia drivers which was fixed pretty simply.

2. Yep. No issues. Started up without a hitch.

3. Yep. Was running DX11 under Win7 as well.

4. Haven't noticed anything major either in performance or graphical quality between either version of Windows.

5. Windows runs somewhat faster now than under 7. Most apps run about as well as they did under 7.

6. Nope. Hasn't seemed necessary at this point.
