What is the best opperating system for games?

Depends on the games but most current commercial games are windows exclusive. Windows 7 will be good for newer games.

If your talking about current games. Windows 7 x64, the difference between Home Premium and Ultimate is negligible.
Older games, it will depend on how old, Windows 7 will run most things designed to run on Windows, it may struggle with DOS based games. But you can run those in Dosbox anyway.

Windows 7 x64 at least professional. Because the home premium didn't have the possibilty to run old game in xp service pack 3.

Windows 7 x64 Professional

Why? DirectX.

Mac and Linux do not have DirectX support (at least officially). Linux can run Wine which has DX9.0 emulation but the games selection is limited and buggy in most cases.

Mac is becoming a gaming platform slowly but surely. However, as it stands now the selection is too limited to be a viable gaming platform.

I think all OS are equally accessible for playing games so you need not to make any special choice for it..........

First you need to figure out what sort of games you want to play.. With Windows its essentially the hardware flexibility which makes the battle heavily in its favor.. You can basically choose what hardware you wish to purchase, even assemble them together yourself, install the OS, install some basic drivers and you are done.. Not so simple with the other OS's.. Also, you can basically keep upgrading your hardware or add new devices without any much hassle.. Again not so convenient with Mac or Linux.. Thus, Windows is the clear winner over here.. As for which version of windows, if you have a somewhat modern PC then Windows 7 64 Bit (anything except starter edition) is the one to get..

If you have 2Gb RAM or less them Windows XP is better 3Gb+ Windows 7 Home Premium 64bit

Windows 7 x64
The reason is clear: DirectX
For older games if they don't run good or at all, just use Compatibility mode. That solves 99% of the titles you might encounter...

currently win7 64 pro or ultimate. very few backward compatibility issues. i only know of 4 games (post 2006) that wont install on it and there not very good 1s. you will have problems with games that install with 16 bit installers but you can VM them with dosbox or similar if you really want to play them.

in a few months windows 8 will arrive and that is supposedly more geared to gaming.
