another how many?

[Jobistober]

As many as you want. With a system like that, your bandwidth will be the only real concern. I have my old socket 754 system running my GunGame server. It's got an old 3700+ 2.4Ghz proc and 2Gb of ram, and I can have 5 different games being served at the same time and they all run smooth. But the bandwidth becomes a factor if all the games are being used simultaneously.
