Hardware for CFD Academic Enthusiest

I am a recently graduated uni student who is about to embark on a rather low key development project with my friends race team. I will be using CFX to develop a new aerodynamics package for his vehicle and would like some advice regarding suitable hardware for this sort of operation.
My basic questions are:
CPU-Quad Core vs Dual Core? Processor speed?
Ram-Speed or quantity?
HDD-Speed important here?
I am building a dedicated coputer to run these operations and will doing pre and post on my current workstation. I am limited by budget to 775 socket hardware, however, this should give me the grunt I need to solve 10-50M Node problems.
e5300 OC @ 3.6GHz
Asus P5QL Pro
8GB (4x2) DDR 2 800MHz RAM
2x500 WD Black RAID0
Thanks in advance.

You are going to have a very difficult time getting enough ram to load a 50M node problem on a desktop machine without disk thrashing. That is a fairly large problem and I would suggest instead perhaps springing for a few diskless 1U server nodes. The setup will be a bigger hassle but you will be much happier with your capabilities in the end.
