Additional Comments:

I do two things on my computer in equal ratios. I write from six to eight hours a day and do the same with gaming. I'm at my desk a lot. My current rig is incredibly loud, though the extra fans I had to slap in to keep the graphics card cool - the fan broke - probably aren't helping.

I'm looking for performance primarily, but I'd also love to try and keep this computer quiet, or at least quieter than the one I'm using now.

For reference, the game I play most is StarCraft II, but I'll also be hitting up Civilization 5, World of Warcraft and Diablo III.

After getting some advice on my initial build, I thought it'd be worthwhile to post the revised version for any last minute feedback   I've got $50 left to work with if there are any obvious upgrades

Thanks in advance! I don't post much, I love lurking on this board
