If I recall correctly from past research, a Studio XPS 7100 has a 425W PSU, which is terribly low. The specs will be fine, I just worry for the PSU.
I, too, am kinda curious why you -must- buy specifically from Dell, and are unable to shop around? I'm not exactly a fan of buying prefabs but Gateway actually seems to be a little more on the ball in terms of "bang for your buck" when it comes to gaming rigs than Dell is. I still think customization websites or building it yourself is the way to go, but if you -had- to buy from a company, Dell isn't the best company to buy from. For "gaming rigs", and setting aside the fact that you're overpaying (and simultaneously ignoring Alienware for that reason), and after stuff like Sager, I'd say Gateway is your best bet, then HP.
So out of curiosity, why is it that you -have- to buy specifically -from Dell-? Company credit with them or something?
