I have no problem with my GTX650 dual monitor.
Yeah, the start menu is not too bad. Still irritated about my crappy My Computer Shortcut and forced to pin [my name] folder in the folder jumplist instead of unhide on the desktop. And have to pin Control Panel to my taskbar.
Best thing about win8 is the ability to install random free games without any regard to its quality/security/etc.
Hope taskbar can be updated to launch Metro App and visible and without losing visibility. Yes, I don't use Alt+Tab and I dislike to auto-hide my taskbar.
