There is not not much discussion about hardware on the OpenFOAM forum

I am currently playing with OF in a virtual machine under XP on an oldish Intel Core-duo E6300, but I plan to move to new hardware soon.

I don't know a lot about computer hardware - my questions are:
- should I go for a single or dual processor system? (can I run on one processor and then add another later if I wanted more power?)
- what processors are recommended?
- are there any brands/processors etc that one should avoid for compatibility reasons?
- whats important when buying RAM (apart from the size)? I think I'd start with 16GB but select a system that I could expand to say 32GB if I wanted to later.

I am starting out with 2D problems with less than 100,000 cells but when I build up to 3D geometry I expect 5M cells is likely.
