Hi there,
thanks for your replies. In fact Windows 8 gives no boost to games. According to some article I read on tomshardware, 8 is as fast as 7 in most situations.

So: No, there is no need to switch to 8, when using 7.

If you are interested in additional features which are offered by the 8 pro version (e.g. hyper-v, faster boot etc.), this might be a point for someone to switch.

If you still run XP you may take the chance of getting a cheap 8 (til end of January 2013).

Interesting fact is: Only CloD does not work. Every other game (I own) does its job quite well @8.

@Airhog: If you uninstall all previous installations of .net Framework @8, the installer does its job, but CloD only starts for a second (steam says "Playing Cliffs of dover") then quits.
