Yeah, that one's a bear. I just finished one on my kids' Sempron 2800+, and even my overclocked A64 3400+ has been folding away on one since mid-day Sunday, and is still only 68% complete.
I believe it's a 396 pointer, but it looks like Stanford's down at the moment so I can't confirm that.
You're correct, it's 396 points. We seem to be averaging around 80 points/day on it.
