Definitely the best little GPU you can buy right now, ridiculous prices aside.

Asteroids WU ~43 min
PPS Sieve ~26 min while running 2 at a time

There are many versions and they all have a little different clock speeds. This is mine....

They use all their power and can be tough to keep cool though. I might recommend one with 2 fans.
