I just wanted to post my experiences with my first iteration of this card just so that others were aware of some signs that they may have a defective card.
Yes, I know this card doesn't even have preview drivers yet, but oddly it worked best under Windows 8. The issues I encountered were limited to random BSOD after the system sat idle for long periods of time (even with power saving features turned off like turning of the monitors and sleep). It seemed to run games just fine. The only odd-ball thing I noticed off the hop was the factory set clock when I opened up Overdrive was the 3D clock was set to 600 MHz. Even after that things were okay except for the random BSOD.
This is where things went south fast. Running a game like Battlefield 3 or Mass Effect 3 at 1 GHz (factory overclock) resulted in a crash (3 screens, 1 different colour per screen) as soon as the GPU's 3D clock kicked in and the game was going to go full screen. I checked voltages, I checked card temperatures, everything seemed okay (except for the well documented VRM issue) with the card. My system voltages are stable, temperatures are nice and cool (my CPU generally only hits 40c if it is really hot in the room.) I disconnected devices, tried with only one monitor, no banana. So I downclocked the GPU to 925 MHz. Battlefield 3 now loads as does Mass Effect 3. Battlefield 3 does crash after 15-20 minutes with a black screen crash, but I was expecting that to no doubt be another issue un-related to the card itself.
So what am I doing? I'm taking it back to the place of purchase and praying that they have a newer revision of the card with the VRM cutout on the backplate and will see if the store will test it before I take it home.
