2K isn't bad on newer ATI cards (approx 190K per day on HD 6970), but it is rotten for any CUDA boxes (16K/day vs 120K/day on PG with a 9800 GTX ). Even at 6K per WU, PG pays twice as much -- at least for CUDA gpus. So, unless you are going for a milestone and don't have an ATI gpu, PG's PPS is still the place to be with CUDA cards.
