LAMMPS on GPU

Dear Developers and Users

I’m going to buy a GPU to accelerate my simulations. In this way, GTX 1080 Ti is the fastest GPU (of course in the Geforce series). However, I’ve just come across the Titan V, which is said to be majestically very fast. But, I’m afraid of that kind of GPU due to the following concerns:

(1) Titan V is developed based on Volta architecture. Could LAMMPS be compiled upon that architecture on a GTX card?

(2) The NVIDIA announced Titan V being of extraordinary 110 TFLOPS calculating power? That 's a practical statement?

(3) Lastly, I’m not sure if there are other determining factors other than TFLOPS to judge over GTX card upon having other items equal, such as CPU or RAM.

Any hint is welcome.
