I think it's a bit stupid to overclock a GPU like that, since it doesn't cope with the real problem: the ugly bottleneck that AGP is. Even AGP8x (which doesn't work reliably most of the time yet) does not allow for enough bandwidth to effectively render anything from system (AGP) memory. So it's basically a very fast and quiet graphics card, which is way too expensive (I wasn't planning on spending that much on my computer at all, and I still need a new CPU, motherboard and RAM). But I guess a lot of people will want it anyway, probably just because it's cool to have a water-cooled graphics card.
