I've got 2200-2500 to blow on a good gaming rig. Saving 300 for a 22 inch widescreen monitor. What would you get? I want to stay with intel core 2, and don't plan on OCing a lot. I'm sure y'all can come up with a better rig than the 2500 gamer showdown in Max PC.
From New Egg, there is a perfect example of the 250G being the sweet spot, 200G is $70 dollars, 250G is $74 and 320G is $94. This seems to be fairly consistent, the price increase between 200 to 250 is far better than the price increase from 250 to 320. It could be $60-70 dollars depending where you pick it up.
What type of sound are you looking for? The P5N's have onboard sound, which is supposed to be good, you could scrap a sound card for it. From the above quote, that's an 80 dollar savings. You can purchase one later.
