I got the 8800GTS for five-boxing. The 8800GT would have been fine but the GTS is a double width card with a much more substantial cooling system on it. It (allegedly) runs quieter and that was important to me.

I just bought the cheapest one. As I'd already over-specced the card, there was no need to get one that was overclocked. Besides, the overclocked ones would probably have been louder which would have defeated the object of going to the GTS in the first place.

BTW, I'm very pleased with it
