R7850 Power Edition 2GD5/OC and Afterburner + Driver Issues/Concerns?

Question

I just got my R7850 Power Edition 2GD5/OC today, and did a fresh install of Windows 7 but just had a few concerns and issues so far:
1. When using the latest beta (12.11) from AMD, Nexuiz seems to cause the system to BSOD. Kombustor, BF3, and other games didn't have any issues, so I just found this strange. However, these are beta drivers for a reason I guess. In any case, 12.10 seems to work fine with Nexuiz, so it definitely seems driver-related...
2. The highest Core Clock limit in Afterburner is 1050MHz, the same limit in Catalyst. Since this is a PE/OC card, I would've figured the limit to be way higher than this by default? I tried enabling the unofficial overclocking method (t=338906 on Guru3D), but this just caused Afterburner to not have/set any values for both Core and Memory Clocks. I then took a look at this guide (t=359671 on Guru3D) and put the 2 .dll's in Afterburner's folder, and it causes it to be able to read and set clocks properly, however, there is an insane amount of flickering at times (I think due to switching of clocks?).
3. MSI LiveUpdate 5 can't read my card BIOS or get any information about it aside from it being a 7800 Series card. I was mainly interested in checking for any VBIOS updates, and if it helps, GPU-Z tells me my BIOS Version is 015.015.000.002.000000 (113-xxx-xxx).
4. The dust-removal fan tech, or more specifically, the fan reversal spinning doesn't stop after 30 seconds if no GPU driver exists in Windows. In other words, if I'm using the Standard VGA drivers, the fans keep spinning (in reverse I'm pretty sure) at what sounds like full power.
I have CPU-Z and GPU-Z validation URL's in my signature for any more system information, and I also have a hec 585W PSU.

For 1. you already solved this yourself to be driver related.
Yeah, I guess I was just more or less curious if anyone else had a similar incident with these drivers.

For 2.: Use Driver Fusion in Safe Mode to remove current VGA drivers.
Then install latest drivers from MSI
Try again
From what I understand, those are just the standard Catalyst 12.8 drivers from AMD? In any case I saw http://forums.overclockers.co.uk/showthread.php?t=18431335 which in short said to make a desktop shortcut of AB with -xcl, and download some patch; and doing both of those actually worked on Catalyst 12.10 drivers. So everything (so far) seems ok, no flickering or anything.

For 3.: Upload current vbios to a filehoster and post link as well as add S/N
VBIOS: http://puu.sh/1i8DU
S/N: 602-V273-030B1207046208

For 4.: That is normal, it runs at full speed until fan control kicks in with the driver.
Ah, k
