Yea, im happy with my build. I will be staying with the g.skill ram. I will also be getting a quad core, as you said, it is more future proof.
As for sli, I agree it's not really worth it at this time. I am still trying to decide between the msi platinum and the ds3r. The only difference between the 2 is wether to sli proof or furture proof.
When newegg does work for you, let me know what you think of the case.
