Server recommendation for my websites?

[Termalhigh]

Hello, I have a forum website(invision board) and need some inputs to select a dedicated server. My forum has 8 million posts (Including posts and topics) in total. Right now i am using Xeon 5260 2 bay chaisis, 12 gb ram, 400 gb SD. I just want to know how can we determine the server configuration based on what factors? Do you know anything about Hostnamaste.com or Regvps.com dedicated hosting services? Any experiences? Where can I read reviews about them?
Thanks

It is a good idea to speak to web host's representative to make sure that you'll receive exactly what you need. I am quite happy using Shifthosting.com dedicated hosting service. The price is right for us, the service is dependable, and the customer relationship is responsible, eager to participate in resolving the problem and prompt.
