Final Suggestions \ Tuneup on $1500 - $2000 i920 pc

After looking over some suggestions here, I'm close to finalizing my build.
This machine is intended for some fairly intensive realtime video work.


I'd like input on the following areas:

1. Storage.

Would I see any real gain from spending more in this area? Performance here is pretty key, but my understanding is that I wouldn't see significant gains by going SSD (and it would be far more expensive).

If I could see significant perfomance gains, I could bump this area up to the $300-400 range. I'd also consider an alternate brand of drives, I've had good experiences with the caviar blacks in the past.


2. Memory.

I'm definitely going with 12gb, is there a brand that I could get cheaper that would offer similar or better performance?


Any other suggestions for economizing are welcome, I'd prefer to stick with a modular power supply, and like the Hanns G monitors quite a bit, (I have another already).
