Wow looks like you have everything sorted out but I'll add my two cents.
First off the 1TB drive. I was going to get a 1TB and then the salesman let me know that for an extra $20 I could a 2TB drive.
and the 760. I have a 660Ti which is pretty much the same as a 760 and I'm not sure if I would keep this card for another 6 years, but maybe if you put everything on lowest settings then you could. I think lowest settings you could go about 3 years and then maybe another year or two after that depending on the game.
And that's about all I can comment on.
