I'm wondering, for a video card like the HD 4870 that requires two 6-pin connectors, does it card draw power from one of the connectors primarily and then when it needs more it draws from the other or is it simultaneous?

I believe it uses both at the same time.

yep, uses both. the reason there are 2 connectors is so it doesnt draw too much power through 1 pcie cable and burn out the cable or melt the insulation.
