I am new to this forum and I wasn't sure where to post this?

I am looking to buy a new SLI bridge from EVGA, but I can not figure out which one will fit properly/look better. Right now I am running

Asus Z87 Pro
(2x) EVGA 780ti SC w/ ACX

I would like to have a gap between the cards for more cooling. I want to put one in the first slot and one in the 3rd slot. Will the 3-way one work and light up? Will the 2-way let me stretch from the first slot to the third slot?

If you look at the specifications it tells you the following;
2 x PCIe 3.0/2.0 x16 (x16 or dual x8) This tells us that ONE card in either the yellow/tan top slot or the next one down will run at X16 speed; that SLI with two(2) cards - one in the top yellow slot and one in the middle black one - will run at X8. (Game wise you will probably never see a difference in frame rates).
1 x PCIe 2.0 x16 (x4 mode) This tells you the bottom black slot will ACCEPT a full size video card, but only runs at X4 and the foot note states it is set default at X1.

This is pretty typical of all boards that support SLI; Only a few over the years have supported two video cards at X16.
Considering this, then, you would want your cards in the top (yellow/tan) slot (the primary PCIe slot) and in the second from the top and the data will flow at X8 - which is still plenty fast enough for excellent gaming.
I like those bridges, too, but I have no idea which to buy etc. etc. If no one else can provide the info here in the forum (and I was hoping Kwa-e had that info) then you might need to talk to EVGA support.

Slot size is independent of the number of lanes, and associated bandwidth, actually wired to it. In the case of your motherboard, there are three slots that are physically x16 in form factor, however the 3rd slot is only wired up to 4 PCIe lanes (from the chipset), so only operates in x4 mode (as detalied in the expansion slots section of the board's specs).

As kwa-e correctly points out, you can't use the bottom slot for SLI, only the top two.

EDIT: Ninja'd ;)
