Oh yeah, I'd heard it had those things but for some reason thought the one with the water block would be better (for liquid cooling).

Can I put a water block on the ASUS?

Watercooling doesn't mean it would OC better...

The DCII has more VRMs, so you can put more volts into the GPU, without frying the VRMs from over-voling.

Watercooling will just keep the GPU and its parts cooler so they won't fry from the heat.

Not even the DCII can run at twice the reference.
I don't know any card which can do that even under water (of the newer cards at least).
It will require massive hard-volt-modding, and extreme low temps to keep the GPU heat at check.

If you plan on something like that, forget it. Plain and simple.

this one is way over 1ghz, stock cooling ...
btw fail score since i really think was made at 1024x768 ...

i think 1 GHz is around the max on average for water. after all at 1 Ghz ur looking at a 30% overclock over ref. which is high on high-end hardware.

well.... my reference evga 580 does 995mhz benchable on water ....

I have 4 cards, two of them can do 1050 core, one can do 985 and one can do 970.
So its pretty much a gamble on what you get.

All right, thanks everyone

EDIT: Can I slap a water block on the ASUS DCII? I'm thinking not since it takes up three slots (it wouldn't fit would it??).
