Don't think zombie mod players even know what server fps does, if you want to go 1k fps, do it on the regular server. BUT, if you do up it to 1k fps, don't add any weird AMX mods, it'll kill any improvement you'd gain in performance and registry from upgrading.
And if you really want a 3rd server, just put a poll up and have people vote :P I personally like the euro server idea, I wouldnt play in it because of ping but I think it could become very popular as we have alot of players who would ping alot better to euro servers.
