No, QE-GPU is not designed to use gaming cards. you need a NVIDIA TESLA (K20, K40 or K80). The code will work on NVIDIA GTX TITAN but performance will be crap. > 3. Or we should go for complete CPU solution? If you do not have enough funding to but a NVIDIA TESLA with proper double-precision support or if you are planning to use the server _only_ for QE then I suggest you to go for the CPU-only solution. > 4.
