motherboard for 3 GPU?

[mastercracker]

looking for recommendations on a motherboard that have sufficient spacing between cards so that they don't choke each other.

saw this EVGA Z68 SLI 130-SB-E685-KR LGA 1155 Intel Z68 but not sure how close each cards will be.

any suggestions?

With the motherboard you suggested, you can probably get away with it if you have 3 single-slot card and good cooling. If you are planning to do extensive hash cracking then your card are not single slot for sure unless they are water cooled. In that case, I would recommend using 2 double-slot cards: 1 at the top and 1 at the bottom but you still need good ventilation. I strongly recommend investing in liquid cooling. It ease pretty much everything once you are settled and the system is still good if you do card upgrade. So instead of cramming 3 high end card, I would put 2 and use the money of the third card in watercooling equipment. Then, if you have the money later, add the third card to your system.
