I think I'll go with 3GB
64-Bit is supposed to be backwards compatible with 32-Bit programs. I have never had any problems running 32-Bit games and software on a 64-Bit OS.
I would go with what the IT guy says, though, because there are some
programs that won't work, and he has probably worked with it before, so therefore knows whats best. Stick with 3 gigs for now, but in the future, I would consider getting another gig.
Your IT guy was wrong about one thing. He said a lot of programs won't work. That definitely is not true. There are few 32-Bit programs I have seen that won't work on 64-Bit. Personally, the only one that I have seen that won't is PeerGuardian 2, but I'm sure there are more floating around out there.
