I've been thinking about buying one of the new Alienware ALX systems, but I need to know whats more important a Dual Processor, or Dual vid cards?. Sadly, I can't add both and that would be WAY to expensive. Also, the processor options are 3.8 Ghz w/ 2MB Cache, and 4.0 Ghz w/ 1MB Cache, although the former costs more (guessing because of the 2MB cache) is that the better choice in terms of performance?. Sorry, I'm new to building custom PCs, anyway, thanks
