No one can tell you which pump serves you better until you tell us how your loop is designed, and with which components.
Ok Fair enough, my setup is as follows

Pump -> D-Tek FuZion -> MCw60 -> ASUS X38 Fusion NB -> MCR320 Rad -> EK tube style res (not sure what the model I think it's the 200) -> Pump

The D-Tek seems to be low restriction and the MCW60 seems to be the leader for low restriction GPU block (which is why I picked it over the D-Tek) I believe the ASUS Fusion block is probably the most restrictive in my loop because of the drop in ID of the inlet/outlet and the MCR320 doesn't seem to get a bad rap for restriction except as compared to the PA120.3 which I don't have room for in my case (P182 SE) so in this particular case will a 655 net me anything? I don't mind swapping it out if I stand to gain a few degrees C (room isn't an issue between the 2 pumps) but if my pump isn't the best for my app I would definetly be interested in knowning and more so if there is a good reason...
