im total begginer to card sharing havent start using it yet, im interested is it better to use this on windows or on linux? coz i have only windows xp and it will be hard 4 me to start learning linux coz i dont have much free time....... best regards....

For SS2, you can use WinXp. Because It's easy to setup and use. NewCS and Gbox can use on WinXp without any problem. Some other protocols like CS2 also support WinXp. But NewCS and Gbox are easy to setup and use it with SS2.
