Thinking about building a new computer. I'm not HUGE into gaming. I usually just play Counter Strike Source. I've been thinking about jumping to a Quad Core. I do video editing with Premiere Pro and Photoshop. Is it really worth the extra money to go to Quad Core for that type of stuff or should I stick with a bad ass Dual Core like the E8400? Right now I have the E4500 on a Asus P5PE-VM board.
