It is faster, I upgraded and notice a more smoother feel. I really did like the Release Preview's Aero Glass look. But I'm sure given time someone will provide a theme fix. I do not like these flat non glass colors and while the taskbar looks fine, window borders just look to much cartoony. But other then that I think win 8 is a very good improvement over 7. I would of kept Windows 8 RP but since the app store was shut down from new releases I had to upgrade to get new apps. Oh well. It runs very nice, Amd released new graphics drivers too so I'm happy.
