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.
My GTX760 4GB model is dropping a lot of "result does not validate on CPU". It's one of the WindForce factory overclocked cards. This is a bit annoying.
