Currently at 6 mag, but still rising quickly.
Here are some numbers @jimbo88 posted earlier:
>My three combine for just over 34k RAC on Universe@Home (link). This currently equates to almost 36 mag, or 11.9 each. Keep in mind this is very fluid. Because of increased competition, this is less than half the magnitude I was getting in May. Also, the mag unit (currently 0.175 +35% boost) can make a major difference too. Also, project selection can really make some big differences.
