Med kun 4 stk. tror jeg godt du kan køre på en 256/256, måske mindre.
Fra en guide på :

Having said all that, and once your hardware is in place, the most important lag free tips are your cvars.
You will find the following cvars in your server.cfg file. If they aren't there, you will want to add them.
sv_minrate should be set to 5000 (setting it to 5000 will make dialup users not be able to play)
Set minrate to 0 if you want dial-up users to be able to play on your server
sv_maxrate should be set to 9999
sv_minupdaterate should be set to 13
sv_maxupdaterate should be set to 30
If you have alot of bandwidth, set sv_maxrate to 0. When it is set to 0, it allows unlimited bandwidth.
According to the Valve support page, the maxplayers should be set around the following:
128K uplink = 2 players
256k uplink = 4 players
320k uplink = 6 players
512k uplink = 9 players
768k uplink = 14 players
1024k uplink = 19 players
1140k uplink = 21 players
1708k uplink = 32 players
