Meh.... they've been going overboard on the clear plastic IMO. If i were in the market for a waterblock for one of these new cards, i'd go with this:
That is what I am using on my 290X and I just ordered one for my 1080 TI. The EK block does not have direct memory cooling, it uses thermal pads. The kryographics block uses TIM plus the Aquacomputer block has better VRM cooling.
In the end all of them blocks are not significantly different. Memory cooling certainly doesn't matter enough.
