No GPU mining for me, but thanks for clarifying the key part of needing to get over the dust threshold first--0.001BTC reward, I presume--and *then* you're qualified to get in line... I see now.
No, the dust reward here is the lowest of any pool at 5640 satoshi (strictly speaking you can theoretically get even less than that as a reward if you get above the 5640, but by the time you get a payout, your share of the block is smaller rather than larger due to pool size fluctuations.)
