1. Probably 2 quad cores, but you are not talking huge improvements.

2. Build 2 servers,or use two motherboards for fewer bottlenecks:-) . With a PC, bottlenecks are a fact of life. You're right to try to minimise, though. Spec your motherboard and disk setup well, network cards, etc.

3. You shouldn't be taking figures from us but choosing and knowing why you chose what you did. You need the study under your belt. You know what you're running. We don't.
