Also available as 64bit under MacOS X used (Bootcamp)!

After I have around annoyed me for years with Windows versions I went in mid-2009 on MacOS X changed.
Thus, I had to forcibly renounce some gaming sessions, since MacOS X is not intended to play. Thus, a small downer on an otherwise perfectly functioning Mac OS is recorded.
In this respect, I thought to myself after so many customer reviews here on Amazon as well as in the media ... the new Windows 7 should really be a noticeable improvement. An attempt would be all worth it.
So do not skimp and buy really affordable full version of the "Home Premium".
Installing Boot Camp runs in my iMac_early2009 both 32-bit and 64-bit without hesitation and took only 25 minutes!
That is excellent, especially when you consider that its predecessor lasted considerably longer. The stability has been excellent.

Had I known that before, I would possibly not switched to Mac and could keep my high-quality PC components :-)

A little tip for Mac users:
Since according to Apple website my iMac24_early2009 is not supported for the use of 64-bit, the following suggestion:
When inserting the SL disk, after installation of Win7 64bit, is indeed mentioned in the note text, that this system 64-bit is not compatible with Boot Camp. Thus, you should proceed as follows to make anyway Bootcamp 64-bit compatible ----->
Open SL disc, open the Drivers folder, open the Apple folder and click on the bottom right BootCamp64.msi. And confirm there under compatibility mode "previous Windows version." Then double-click the .msi and the installation is running smoothly!
Then you should play 3.2 64bit and finished the Boot Camp update.
My system runs flawlessly!

Finally use STEAM again ;-)
