All our GPU UEFI BIOS' are dual mode (hybrid).

That means even if you have older ASUS motherboards with no UEFI even, you can still install the Hybrid UEFI GPU BIOS and it will automatically fall-back to legacy mode!

Only GTX 600/HD 7000 are supported because all partners require support from Nvidia/AMD to give part of the code and support. As such, no partner will be releasing UEFI BIOS for GPU in older generations. Like all things, if you want the latest spec you have to buy the latest tech 😉

Some things do not make sense to me, would someone clarify the following.
Isn't that the same for all manufacturers? I would think it would stay that way until sometime after the release of UEFI 3 when CSM will no longer be an option.
If the mainboard is legacy only, no UEFI, then how would UEFI graphics be selected in the first place and isn't legacy the default mainboard selection for hybrid cards? In this case a cmos reset should select legacy VBIOS, no? Wouldn't "fall-back" be a feature of selecting UEFI graphics, having it fail, then the mainboard BIOS switching to legacy option ROM?
Then why does Powercolor have UEFI VBIOS for AMD HD6450 and HD5450 cards as well as HD7000? Why does Gigabyte have publicly downloadable VBIOS updates for some HD6000 cards and even an HD5000 card?
Anything known about this ASUS GTX670-DC2OG-2GD5 VBIOS with GOP UEFI driver dated mid August?

We're talking about nVIDIA cards. AMD cards can have both versions installed by default so this issue does not apply to those cards. This is specifically for nVIDIA cards.

Where did you see that this card has a UEFI GOP? I can see nothing of the sort.

Thanks Nodens, that helps. My bad, I was under the impression all UEFI VBIOS for now were going to be hybrid type only and the reason for no support on 500 series for example was due to there not being enough ROM space for a "hybrid implementation". So far all i have seen is hybrid VBIOS. I would be very interested in seeing a UEFI only VBIOS, especially the header info. If you know of a link it would be much appreciated.
I think everyone is going to have their own preferences with what they want, for me I would prefer a hybrid VBIOS so I can still run the occasional real DOS session or boot backup software without too much hassle, when needed, while hopefully the UEFI side might bring some usefulness other than faster booting (secure boot for those that want it ;)), such as pre OS boot UEFI applications in the future.

It is not evident by the description alone but if you download the image you will see the UEFI ROM starting at offset 0xF600. This contains the 64-bit UEFI Nvidia driver xx.xx.xx.xx.xx, version 0x1000D, dated 14 August 2012. Maybe it is an early beta, idk, hence my question.

Nodens, your comments confuse me. Most uefi gop bios I find on techpowerup e.g. for gtx670 are about twice the size compared to non-uefi vbios(about 160kb vs 90kb). Therefore, hybrid uefi GOP vbios is no special ASUS patented thingy. These 160kb vbios easly fit in each Kepler card. As you might have read I use myself an MSI based hybrid vbios on my ASUS card.
