Windows 8 so far has proven that it starts up and shuts down much faster than Windows 7. Windows 7 is better at 3D graphics performance but falls behind Windows 8 in multimedia performance. When it comes to browser performance, Windows 8 blows away Windows 7 in all categories. It works faster than Windows 7 with Google Chrome, Firefox and Internet Explorer. When it comes to gaming, both operating systems test the same. Overall, I would say that Windows 8 looks poised to beat Windows 7 in overall performance. Once you wrap your head around the no start button on Windows 8 it is an awesome operating system!
