Which processor do I choose? Just asking for some quick advice here... I'm about to buy a Dell XPS 420 and am wondering if anyone would recommend one of these processors over the other: an Intel Core 2 Q6600 Quad or an Intel Core 2 E6850 for $50 more. I'm not a gamer. I'll have 3GB of memory in either system. I use my PC mostly for mulitmedia, school, and internet. The $50 isn't important to me. I just want the better processor for the money. Thanks for the advice.
