The current version of QE-GPU (5.4) should support Fermi till Kepler architectures. The card should have decent double precision performance. Examples are Tesla series K20, K20x, K40 and K80 all have good double precision performance.

If you are purchasing for a workstation, then buy a GPU having a fan/blower based cooling solution. Stay away from passively cooled cards (e.g. Tesla K80).

If you have limited budget then kepler based Titan , Titan Z and Titan black should have decent double precision performance but at lower costs.<br>
