For a database, the more memory you can get, the better. I've found many machines with 4 gigs of ram to not be enough to get decent performance from a database these days. I would suggest going with AMD and getting a board that can do at least 8GB if not 16 or even 32GB of ram. Even with what I've been hearing in this thread about a 20% speed difference with Intel parts, you will totally be ruined once you hit the 4GB barrier on your Intel hardware. -Alfred * Palle Girgensohn [070910 03:16] wrote: > Hi, > > We are looking at getting a server for running postgresql.
