Yeah ,i seen GeForce GTX TITAN X is very cheap compare to Tesla K40, what about keeping 3 x GeForce GTX TITAN X(which is still cheaper than Tesla K40) instead of K40?

it will give any better in performance basis?

 

>From the pure data, the Titan has more CUDA cores, higher Clock and same memory bandwidth. Therefore 3 Titan will outperform the K40 very easy, but only on single precision usage. On double precision the consumer GPUs are made slow on purpose, so you’d need to buy the expensive Tesla series. For gromacs and namd you are ok with single precision.
