​I've tried the GTX 740. I picked one up to power my display, and for fun
tried it out with pmemd.cuda. It worked, but it's slow. It's about 1/4 of
the performance of my GTX 680​. The 680 is slower than the 780 and the 740
slower than the 750, I presume. So 1/4-1/3 the speed of the 780 benchmarks
seems like a pretty reasonable estimate.
