Nice.
Should be able to get a nice i5 or i7 setup if you build it yourself.

Could probably run a very similar setup for about that price to be honest if you build it yourself. That'll run anything you throw at it. You could sub the i7 for an i5, use an HDD from an older build for your storage, if you're overclocking I'd say stick with the watercooling but find a closed loop maybe? Go with an ASRock Fatal1ty Performance if you're not planning on Crossfiring your video cards and save a bit of loot as well.
