Just got mine from newegg... Its running smooth in CFX with a sapphire 7970 ref card both are OCd to the highest settings in CCC and I haven't seen any issues. I run 5 monitors (5400x1920 resolution) from that card and the only thing I've noticed is mouse corruption on one screen (once). Running BF3 I get average 50fps on High, and 60fps on Medium. Overall I'm quite happy with it. Wish it was 5 Display ports instead to avoid the tearing on the 2 side monitors, but hopefully soon that mysterious hub will appear and our worries will disappear...
I got one from NewEgg. Here is the summary
a) it is the model without cutouts for VRM
b) the VRM as reported by Asus' own GPU tweak application is 108C under load (SWTOR) (thank you QwaarJet for C vs F correction)
c) although the VRM temp seems high, the card is stable (no lockouts, or reboots)
d) GPU temp never goes above 72C
e) I have 3x1080p in eyefinity and a fourth 30 inch 2560x1600 (using dual link DVI). The dual link DVI appears to create some very fine artifacts for blue/grey colors. These look like the noise on a photo with high iso. I will try to replace the DVI cable soon and see if that makes a difference (although it used to work just fine with this cable on my 6950). It was reported before by another user that dual link DVI might have issues. If cable is not the problem, I will try the dreaded DP2DVI-DL adapter.
Overall, mildly happy (no crash, good performance, but high VRM temp and dual link DVI noise).
k. I got a new DVI cable and I still get the same "grain noise" over the dual link DVI connection. I have changed to use an active DP2DVI-DL adapter (the accell variety) and I have no issue that way.
To summarize, in my case, dual link DVI introduces "grain noise". If you want 2560x1600, you need a DP to DVI active adapter. This was the same remark of another user of this forum. So much for me bashing MSI Lignthing on not having dual link DVI...

Silly question perhaps, but did you try a different cable?
I only run 2560x1440 and have no issues. Could be a bandwidth limitation that's being approached...

Same here, I run 2560x1440 and have no issue with the DL-DVI connection.
http://jonpeddie.com/reviews/comments/hp-zr30w-reviewThe color behavior cant be changed in-monitor because theres no scaler. The standard (cost-effective) scalers that are used in monitors do not have the bandwidth to process 2560x1600 pixels 60 times a second and with some exceptions, all 30-inchers in the market live life without scalers. HPs LP3065 was no exception to this rule.
Hence, no in-monitor color management. But, all graphics cards have scalers.
The ZR30w is for the commercial/professional market and as such is meant for attachment to desktops and workstations where there is always a scaler present.
.I have a question for you.
I've currently got a Sapphire 7970 reference model and have the Asus DCUII on the way. I will also be running 5 screens in Eyefinity 5x1 landscape mode. How do you have the monitors connected? Are they all connected to the Asus? Are there any special requirements for setting this up?
I'm debating if I should keep my original 7970 or sell it. The main game I play (iRacing) doesn't have a specific Crossfire profile, so I'm not sure how much improvement I will see anyways.

Again, all you saying the VRM's are reporting 100C+, that is wrong
ASUS themselves said the VRM reporting temperatures was wrong, and they and one other website I know of has taken thermal images showing that the VRM temperatures doesn't even exceed 60C under load, like here http://img193.imageshack.us/img193/7962/cidimage002jpg01cd004d.jpg
The VRM temperatures are fine, the last two pages I've seen people again complaining about 108c etc VRM temperatures, but those are wrong cause like I said far far far before in this thread that Asus uses non-standard VRM's, which have non-standard sensors, so they report wrong given that every GPU monitoring program is written for standard VRM's, not Asus's custom ones
The post from Asus might be right, but consider that a lot of users purchase the cars made by a manufacturer: Asus, then they download the monitoring software from the manufacturer page : Asus' own GPU Tweak and that monitoring software reports high temperature... What is their conclusion ? - that the card's VRMs are hot. Also, if the temperature is reported wrong by the sensor, what good is that sensor ? seems useless to me to add a sensor that will never report the right temperature ... The VRMs are rates to 130C, so it is possible to have VRM temps of 100+ and have no crashes... Also, the indicated image is measuring the temperatures of the back plate , not directly on the VRMs...
Are places still having difficulty stocking this?
I don't think Asus pulled them off the shelves, I think we were just seeing a small taste of cards that were having problems, most likely was user error, somebody else here was having tons of problems till they realized it was their fault and the cards worked correctly then
As for the stock issues, 7970's everywhere are sold out completely, its not just this flavor of card that's sold out
I haven't found anyone who has had any success with iRacing and any of the Crossfire profiles.
I'll do some messing around with it later, hopefully will be getting my DCII in today or tomorrow.
Many reports of DOA and rapid mortality on this card, much more so than all other 7970's both here in this forum, other forums, and reviews on Newegg and Amazon. Just read the reviews on Newegg and Amazon vs the other 7970's and it'll be pretty clear something ain't right with far too large a percentage of this card.
As for the second point, stock issues on 7970 sold out everywhere completely, where have you been for the last 4 weeks? Most 7970's have been in stock continuously for a while now, except for the DCUII which has gone missing from Newegg and Amazon.
Proof in point:

Ive read most of this thread and decided to join. My first 7970 TOP i received 3/16, and after setting it up at stock. I ran a few stress test and it failed within a few seconds. I was a littel confused so i loaded BF3 and i could not run it low settings. I knew this was right because my 6970 runs ultra/high settings. i was one of the people afraid of the VRM temps bc ive never seen a card get that hot. According to the info provided by software. Then i read several threads where people where talking about a bad batch, something about heat sinks not setting properly. However, other reports where the card is awesome but shows high VRm temps/normal. I called ASUS and they said it was a bad card. RMA was done through newegg.
I received my new one 4/13, i played BF3 maxed out for a couple of hours over the weekend. So im sure the first one was bad. The one i have now does not have the VRM slot in the back plate. does this mean i have a older version? Another idea, is if i cut a hole(in the backplate where the VRM slot would normally be) and mount a small fan to blow Air directly on the VRM. will this hurt the current airflow.
