From:

with GTX 660 as a search parm
179.2 GhzDays/Day of mfaktc
(More if it is a Ti)

And here:
https://www.mersenne.ca/cudalucas.php
About 17 per day.

Every little bit helps though in general these cards are much more productive at TF (ie mfaktc).

From here:
https://www.mersenne.org/report_recent_results/
you can current TF work under 1 GhzDay per assignment.

At 2 GB of gpu ram, it's of limited use for P-1; probably ok in CUDAPm1 up to 170M or so.
The 140W max power seems like a lot for the 180GhD/day TF throughput. A GTX1080Ti can run 1200GhD/day at ~180-200W. A 1050Ti is 75W and 300 GhzD/day. The RTX20xx are even better performance per watt.Compute cost of running it, versus cost of buying a more power efficient card, for your utility rates.
It will be slow at LL or PRP, so give preference to running PRP with Gerbicz check. It may be able to run GpuOwl 6.5 or later. CUDALucas does not have even the Jacobi check.
