Well dude if it has to be EVGA you're limited to three options really with water cooling. Reference, Superclocked w/ Nvidia cooler or Hydro Copper (regular or Classy). I would advise you not to buy the HC variants as the Komodo blocks are known to be very restrictive with inferior internals and they are stupidly overpriced. However, if you want a Classy under water the Hydro is going to be your only option as there won't be any other water blocks for it and the reference ones do not fit cause the PCB layout is different on the Classy. Best value for money is reference + water block.
