I had Win8 for several months, decided I had enough......formatted my HD and reinstalled Win7. Waste of Money!I liked the control panel the way it was. Also, the start button is so much easier than dragging your mouse over the top right corner. Here is a link for the MS financial statement for 2002. Does not look good compared with the past. Monopolies often get too big and fail. https://www.google.com/finance?q=NASDAQ:MSFT&fstype=ii
When it comes to 4k display resolutions and Nvidia (at least for now) it will require bare minimum Windows 7. Neither flavor of Vista or XP is supported at this point. And even then, not all hardware is supported on Win 7 or 8 at this time. At least this is true for the hardware I have for Win 7 (GTX 600, or 700 series drivers). Not even Titan supports 4k right now, though it's coming eventually.
