Man, I had been staying away from this thread is it'll cost me money if I keep browsing/reading it. Now ya'll have me itching to go get a 930, mobo, ram, psu, case, hell lets toss in a video card too. Bah I hate ya'll....
LOL! If your looking for a reason not to buy check out the threads that have folks looking to upgrade from a Q6600 and play mainly BC2.
If your coming from a slower CPU (<3GHz) or do video editing the i7 will be more bang for the buck from an upgrade. You can save a few $$ by going dual channel (4/8GB). The X58 platform is a bit more expensive but very flexible when it comes to upgrades (3x SLI/Crossfire, Gulftown, 1/2/3x channel memory).
