I don't think one version is better than the others for games, but you can take a look at comparison chart.

There is no difference in game performance among the various Windows editions. The only reason to get a version beyond Home Premium is if you need support for more than 16 GB of RAM (impossible on current MacBook) or advanced networking features.

as far as I know then the only thing which differ in terms of windows supporting memory is
32bit vs. 64bit where 32bit only support 3.2Ghz

The maximum amount of physical RAM for a 32-bit OS is 4 GB (not GHz). And Windows 7 Home Premium x64 supports only a maximum of 16 GB of RAM. Professional and Ultimate support up to 192 GB.
