I plan on running 2 8800 ultras ( bfg pre waterblock installed ) and a athlon 6400+. I am thinking the pnly effecient way of cooling the system would be water cooling. I am afraid that a single radiator (single 120 mm radiators) would not suffice so i was thinking of adding a dual 120 mm radiator. So the setup would go pump 1 > cpu > single 120 mm radiator > pump 2 > 8800 ultra 1 > 8800 ultra 2 > dual 120 mm radiator > reservoir / flow meter > (back to) pump 1 Would this work theoretically and practically? Do i need the 2 pumps or would one 415 gph pump be enough than 2 ~375 gph pumps. Thanks!
