How many games could run on...

[HSGaming]

Hi there.

I was wondering if anyone would have a rough idea on how many css servers would run on the following box:

Fedora Core release 4 (Stentz) Kernel Version 2.6.14-1.1653_FC4
1tb bandwidth, 100mb port
Intel® Pentium® 4 CPU 2.80GHz
1024MB ram
80GB HDD

All servers with 12 players and at 33 tick.

Thanks

depends on the tick, fps, and a few other bits to do with the server settings.
I have an AMD 64bit 4000 and can only run one 18 man server at 100 tick 500 fps without it going over 90% cpu

As I said, all servers 12 players at 33 tick.

Server settings @ default.
