My friend in the UK ran quadrant and got well over 6500... It's really a beast. The only problem is the size. I've already found the Galaxy s3 to be somewhat larger than I actually need at times, don't see myself with the Note 2 and using it for calls regularly or taking it in and out of my jeans pocket. It's a really nice phablet though. 5.5" screen, quad-core with 2 gb ram, LTE and the new s-pen is very precise.
Would I recommend anyone trading in their GS3 to get it? No, you'd be a fool to do so, unless you want the extra screen real estate. It may be better than the Galaxy s3 at a lot of things, but it's incremental, I'd advise waiting, especially as the Android market is about to get increasing competition. We're seeing the HTC OneX+ coming, the LG Optimus G, the LG Google Nexus, and the HTC DLX. My personal preference would be the HTC DLX, which will be 5" Super LCD2, 1.5 to 2 gb RAM, HTC superb build quality, 12 megapixel camera, and the quad-core Snapdragon S4 Pro with LTE which will most likely beat the Exynos Quad that is in the Note 2.
If you can't wait, by all means get it, but the Note 2 isn't the beast I thought it would be.
