See? Forgot about the cache on the 3000. I agree, the extra 512 makes a lot of difference. Go with the 3200. It's a much faster processor, all around.
My prices toward the end were a little high, so you can probably squeeze a little more out of the $2k, like Gotenks has done. Ultimately, though, a lot of it depends on your preferences.
Side note: I'm only here again because I can't sleep
