Hi Diederick

It really depends on your budget, to our experience the best value for money (from the top solutions) is the Tesla K80. This actually includes two GPUs in one card, it has a lot of memory and we find it works very well for high-mem applications as well. 

We will release a GPU version of probtrackX in the next FSL versions and our experience of that with K80 has been great. 

Cheers
Stam
