How can I get the most out of my new GazP7? It has the base i7 offered and I bumped it up to 8 gigs of ram. But being an i7, it's a HUGE bump for me as I come from a dual core pentium processor. But I noticed, I am playing a java based game, and watching a dvd at the same time. The java game slows down tremendously, even at mid settings. The game by itself is laggy even when the dvd isn't playing. The i7 has the HD 4000, which is supposed to be a huge improvement over HD 3000. I already installed the System76 Driver's off the setting's program. How can I make this the i7 it was meant to be?
Edit: How can I upgrade which version of ubuntu I'm running? When I go to edit my profile, I get a notice saying I need 50+ posts.
