Some 9800 Gx2 questions

[500r420]

I just bought a 9800 gx2 video card and have a few questions:

1: What is the best way to adapt to the 8 pin power plug? I have two 6 pins but no 8 pin. I would like to best divide the power amongst the different channels of the psu.

2: What is the included, thin, 2 pin cable used for?

3: This product is brown box nvidia made board. Do they have a warranty on their products?

4: Does anyone know how much, if possible I can overclock this card? I am thinking about adding a 120mm side exhaust right over the top of the card (where most of the card exhaust is) into the side fan slot on my case.

Thank you very much for your help in advance.

So I was looking at some of the cables that came with the card, none of them which I need
It seems pcie has 3 yellow cables, and 2 black and 1 brown. Pcie 8 has adds a brown and a black.
I'm not an electrician but I guess the yellow is +12v and the black is the return and the brown is who knows what?
The pcie 6 fits into the pcie 8 and leaves room for 2 extra pins so I just need a way to add one brown and one black cable from molex or p4 or whatever

i hit 802mhz on mine, i think i got lucky and 750mhz is more in line with what you might expect.
