Well ya, I have a Tri Crossfire setup, Im pulling about 900 M/Hash/s Im also have a friend who is helping me with about 400 M/Hash/s ... Any idea how long it would take to see a block?
with 900MH/s, you don't even expect a block every month at current difficulty. You could potentially go months without ever finding a single block while difficulty continually increases.
You are much better off in a pool with only 900-1300MH/s
