I want to build a high end system. Not being a gamer, I assume that I don't need a GPU.

I assume that I can use the current leaderboard build (Intel Core i7-4790K) & just omit the discreet GPU. Correct?

I run Ubuntu 14.4 & use the system for web browsing, Thunderbird mail, Libre Office, and some Windows apps via Wine.

No video editing, or gaming.

I just want a fast, responsive system. Skipping GPU & sound card gets me to about $750.

Am I missing anything?
