here we go again.
mainstream-kids who think max is the best.

do you have any idea about the server files to claim they need 16gb of ram?
i just say it once because I'm tired of these kids who claim they know it all and that think bigger-better-best is everything. yeah..go buy your old crappy cars and visual-tune them until you got a rocket under your *** (only visual of course.lol):
a 8-gig machine is enough to run a server with 1000 players (and all zones loaded).
the gameserver itself has restrictions. so if you want to increase the slots, you'll have to run a second gameserver/agentserver anyways.
stay at 8 gig of ram. cpu is noooot that important as you think. as long as it's a quad it's enough to sustain the 1000 slots.
everything above is just pure bullshit (same as the endless convos i had about sql server 2008R2 and sql server 2000)
300-bullshit!
I've secured/configured servers with this hardware:

and it's fairly enough for 1000 slots.
if you think I'm wrong, prove me before you come with your 16-gig hexa-core **** ****
