I know that it uses the reference GTX 680 PCB and everything. I was just curious if any of you guys had them with waterblocks and which one you had. I really want the nickel Heat Killer Hole Edition but can't find it in stock anywhere. However I am looking at the Aquacomputer aquagraFX Nickel and EK GeForce 680 GTX+ Nickel. If you guys have any input on any of these that would be much appreciated.
