System Resources for EWQLSO Platinum

[Composer Guy]

Hey, I'm planning on buying the CCC and I'm curious as to what you guys consider an ideal set up (within reason) for running such large libraries.

I was planning to build a computer, 2.8ghz quadcore (intel i5 760), 12gb ram, and a 1tb harddrive. I realise this is more powerful than the recommended specs but I'd hate more than everything to have the computer struggling to play back the samples. Would this be enough to play back entire symphonies, etc.?

Also, would there be an advantage in Platinum Plus (which includes 24 bit and 16 bit samples) or should I just go with Platinum which lacks the 16 bit?
