Yours: 60MH, 590w, 1MH/w
Titan: 380MH, 1300w, 3.4MH/w
Titan is significantly better
you dropped a decimal point, both of those MH figures would be per 10 watts, not per watt.
Titan IS still quite a bit more efficient (when it hasn't died yet).
Alcheminer figures were around 250 MH for 2500ish watts, I don't remember the exact numbers but they're very close to that same 1 MH per 10 watts figure the A2 manages.
Personally, I'm waiting for the A4, since tapeout on it was "leak" announced a while back.
