Out of the above brands, only the XFX and Powercolour has been confirmed to have chance to unlock.
VTX and Powercolor, both the same GPU under different names, don't bother with XFX, crappy quality.
They are all exactly the same as Sapphire makes them for AMD then ships them out for individual branding (stickers). Obviously a few don't have lasered off shaders, but you get my point.

But all the reference cards are made by Sapphire regardless of brand

XFX have put 1250Mhz Memory IC's on Tahiti LE GPU's and ran them at 1250Mhz where AMD advertised them as 1500Mhz, they also tend to use Elpida IC's far more than other brands.
Seemingly they cut costs.
According to Gibbo, AMD sell GPU's to AIB's in different ways.
GPU chip
GPU chip + Ref- Board
GPU chip + Ref- Board + Memory IC's
GPU chip + Ref- Board + Memory IC's + Ref- Cooler.
They might only be selling the latter, but i wouldn't risk it given their history when VTX / Powercolor are available to him and probably cheaper.

Except you didn't quote the part which Gibbo said in the same post that at the moment all brand can only acquire the card as a whole which is pre-assembled by Sapphire.
forgot about that.

I've fitted the Gelid Icy Vision Rev2 cooler onto my VTX pre-flashed to 290x last night, and while it did an excellent job in taming the GPU temp (75C max when overclocked to 1200MHz with voltage on 1412mV), the vrm temp can easily go out of considering hitting 100C+ if using higher than 1.350mV on the voltage. I think I would need to get a bigger sink for the vrm.
I've got one on the christmas list. Did it come with enough heatsinks to cover all the chips?
What's the best tool to measure VRM temps?
Thanks a lot.

Yes it has enough 16 ramsink which is enough for the 4GB of vram. The vrm2 you just using the imagination with the leftover small sinks and thermal as well as the long thin heatsink for the vrm1. But if I were to do it again, I'd probably just uses these instead:

Especially the vrm heatsink.
No matter what I do I cannot see POST when booting from this card. I've tried various 290X bioses and I've tried it in 2 different rigs. I've never touched the 290 bios but even that doesn't show POST. Getting very frustrated by this. Can I please get some advice before being forced to return it.
Thanks.
Thanks.
I don't know, sorry.

What monitor/TV are you using. I know some TV/Monitors don't show the post due to the low resolution during post. My daughters been 1 and that's with a NV card in it. However the main TV in the living room does display it correctly, that's on my rig with a VTX3d 290x in it.

It's a 42" Panasonic - it displays the bios fine when booting from my GTX660. I'm going to update the motherboard bios tonight as I realised it's on an old version.
The mobo is a brand new 990fx Sabertooth from Asus.
My previous mobo was an ASUS P6T. With that mobo I could get to and see the BIOS. It lost the image just after the first bit of POST (past the 'press DEL to enter bios' prompt) and didn't regain it until Windows booted.
The problem on the P6T echoes symptoms reported elsewhere online that is rectified by a GPU bios change but it had no effect in my case no matter which one I tried, and the problem persisted in the 290 switch position as well.
