My dedi server might be overkill. What do you think?
 

Right now I have a forum with approx 18,000 registered users, 1,000,000 posts and usually several hundred concurrent users online.

I use no more than 100 gigs of band per month.

My dedicated server (elite) with Hostgator gives me 2500 bandwidth, 4 gigs RAM, etc. It runs great I just wonder if I couldn't be paying a lot less per month for a VPS and still get the same performance.

Could a site the size of mine run just as well on a much cheaper VPS?
