T7600: for mission critical trading and multi-tasking

Dear All,

I'm about to upgrade my trading computer to a DELL PRECISION T7600. This computer is to be used for mission-critical trading applications. (Note: thank you all for the advice you gave be back in 2008, it was very helpful, I just re-read it you guys have a lot of wisdom).

Priorities are:
1. reliable/i.e. never crashes.
2. in the event of crash, fast recovery and protected data.
2. good for multi-tasking. This means running tons of normal business applications at the same time, MS Office, Skype, Matlab, Adobe, Bloomberg, Firefox. Small increases in responsiveness will help me keep my sanity.
3. limited number crunching, but nothing major like video encoding, etc.
4. note: overkill is ok (but I want to spend $$$ on things that will help).

My proposed build is below. Some of my choices were arbitrary, i.e. I didn't know the difference between the choices. Any help you guys can give me would be greatly appreciated (for example, which processor, etc etc).
Specific questions:
1. Is it better to spend money on Dual processors or one-faster processor?
2. Hard Drive configuration: SAS is best choice?
3. SSD/RAID1: can I have a SSD as the boot drive and then RAID1 on drive 2-3? or is it better to have RAID1 on boot drive? or some other configuration?
