First picture is the best option. The righthand option with Y's - as already pointed out, water will always take the path of least resistance, so including slight difference in tubing length and bends when using the Y's, one card will get more flow than the other... but more importantly, when splitting the flow to each block you half the flowrate, velocity and turbulence thru each block, and thus reduce the cooling performance of the waterblocks.
