Firepro Cards

Hey all, been doing some searching and haven't come up with much. I am considering a Firepro wx5100 for my Solidworks stuff. I am curious as to what mh/s I would be getting with such a card with 8gb of GDDR5. The card would be supplemental to my 390x when mining.

system specs:
FX-8320 oc 4.1
16gb 1866 RAM
Sabertooth 990fx r2.0 Mobo
Corsair H110i GT cooler
Sapphire tri-x 390x
Seasonic snow silent 1050w psu

Getting 28-29 mh/s ether
580 ish mh/s decred

I believe I am running Claymore 8 but not positive.
