Quote from johnedit:
Should I get a dual Xenon setup or one of the overclocked gaming machines?
Depends. My main problem with "gaming" machines (i.e. non-xenon) is that you wont get ECC ram. FLicking RAM will wreak havoc to any financial results - a bad pixel does not change a game. I stick all ECC memory for my work machines.
And you can put in standard components.
