3 ASUS ROG MARS cards are ordered. This should be close to 20 kHash/s YAC mining power - all on one mainboard.
I'm curious to see what your results will be with those as I'm currently experimenting with Yacoin and GTX760's (one 2gb and one 4gb). I'm one bad decision away from dropping some cash and putting a proper rig together.
I have 6 slots...should be able to run 6 r7 240s on my board. But yeah, those Mars look amazing!
