Quad SLI question

[terrelljames91]

i just bought a asus P5NT SLI mother board, it uses the 780i chipset, which has 3 PCI slots, im new to SLI and im trying to figure out what i need, and a little help would be very helpfull, first theres 2 blue and one black slot, what is the difference if i go two cards what color do i use?, and also i was thinking of getting GTX295's which are double GPU's will two of these work in quad SLI mode in this board? thank you

If you use a single card, that would operate at full x16 where as if you use two cards, it will go x8 in each slot. Other than that, GTX295 is compatible with SLI mode.

on this board there all suppose to operate at 16X i understood that, but im going with two cards, do i use both blue slots? or a blue and a black?

The blue is version 2, so faster.

Use the blue if you can.

P.S. You'll need one hell of a power supply.
