Could be... The blocks are almost identical though.

Any idea on a price range? similar to the GTX 580 with Hydro Copper or Cheaper/More Expensive?

One question though: What is the point of this thing if there's no voltage control? I still see 2 6pin connectors. If the stock air cooling keeps the card below 70C and is super-quiet, then why would anyone buy this thing? 40C doesn't matter if it doesn't overclock. One of the threads had someone using dry ice to keep the card in the teens under load and it added ZERO mhz to the overclock.
I seriously hope the non-reference models do something with this voltage because I know these cards are beasts but if non-ref's don't address this issue them I'm seriously going to start to worry...
Please help us EVGA! thinking.gif .....Classified Ultra 4GB- 8 VRMs, 6pin + 8pin connectors, 1.35v max voltage, 1400+ average overclocks = king.gif

GTX 680 actually gives better performance when its cold. As it gets hot, drivers start decreasing the core clock to lower the temperature. Waterblock might be able to help in this regard.

Yes. transistors are more efficient at lower temperatures.

And the fact that the warranty is still valid. Which is a big deal for some people.

I like the look, but it will be overpriced like every watercooled ready to use gfx card. Ofc easy of use and warranty matters more to some than saving a few dollars/euros.

I'm sure they will be $650-$700 and yeah it's nice to just plug them in but in the long run they are harder to use in another system unless it's setup for water or sell for that matter, I ran into this with the BFG GTX 280 H2OC it's better just to install it yourself, EK blocks are cheaper $110 plus you still have the air cooler.

Primary tests on the reference have shown no where near of an improvement to justify water-cooling. Tests have been done with 40% fan speed and 85%-> keeping the card at 59 or 60C under load. There was at most 5-10mhz increased stability. And the dry ice runs, the thread is long, don't feel like going through to find the post, but literally had the temp in the teens/20C under load and didn't do a single mhz faster than at ambient temp. Transistors may be more efficient, but how much more? If the card already runs in the 60Cs under load with the ref cooler, then it's definitely not worth getting a WC setup for this card just to draw a few watts less of power. It's the voltage cap that's set way too low. If this is 8+6pin then maybe the dynamic voltage goes a bit higher on it's own, but manual voltage control is what we need, or at least a significantly higher setting for the max dynamic voltage.

Jacob didnt tell much about the performance but he said that with this block GPU load temperatures don’t go above 40C.

man I wish they would have just fixed that damn connector sticking out, maybe used a custom design to make the connectors flush like the older hydro copper cards. that honestly looks like one of the best full cover blocks I have seen thumb.gif
