quad vs duo

I know this has been discussed here before (and I did see the Tom's Hardware post), but I was wanting a little more info/opinions about the Intel Quad processors vs. the Duo's. In particular, I am referring to the E6850 vs. the Quad Q6600. I went throughout the entire performance chart (Tom's) and it seems the E6850 out performs the Q6600, especially on FPS (which is my focus). But that said, I have seen where some folks believe that in the future the Quad Processors will outperform the Duo's in FPS and performance. What I would like, are some opinions on this issue. I will be purchasing my DS Twister Pro this weekend sometime and I would really like some feedback. I should have done this a week ago. Me, the procrastinator. I guess I'm leaning toward the E6850. What are your thoughts?

Ok, I got this thing figured out. If you have a game that will match the wide screen monitor's resolution, then its no longer wide screen for that game. It’s just a really big window that shows you everything and completely fills the screen. If your game has less than what your monitor is set at, then your images will seem a little squashed. I found many of my old games titles have the 1680x1050 resolution, and those games perfectly fill the screen with all images sized proportionately. I have a few games that play right under that setting and I can hardly see any "squashing". Only draw back now is the heat a 22" monitor throws off. The Samsung 226BW looks beautiful and I’m seeing things in my old games I've never noticed before. And it only costs 300 bucks!
