So, get this: while Windows 7 only accounts for 6% of the global operating system market, 23% of Steam gamers are using Windows 7!
The breakdown shows a lot of statistics, including average processor speed (2.5GHz) and NVIDIA (65%) versus ATI (30%). You can even see the split between 32- and 64-bit versions of Windows 7: if you click 'Windows Versions', all the flavors drop down 64-bit has 15.6% of the total share, while 32-bit has 7.45%. In the past month, the Windows 7 64-bit adoption jumped 2.5%, while Windows XP dropped by 3.2% a sure sign that gamer geeks are finally migrating away from XP (and that Santa brought them shiny new computers!).
