    They were NVIDA GeForce GT cards. The one I'm using now is the GT 740.

    Have you tried installing a video card in a computer that has UEFI and Secure Boot enabled? I did and the computer wouldn't boot. I had to remove the card to get my computer to boot. After searching in Google I found out I had to disable Secure Boot and enable legacy bios to get the card installed. You are right, the card doesn't have to be UEFI ready but your not going to boot your computer if you can't turn off Secure Boot.
    Yes, every computer I've built for the last 3 years has been UEFI with SecureBoot, and none of them have had any issue with any video card.. NVidia, intel, ATI.. The only reason that would be necessary is if the card needed a firmware update for the CPU or Chipset in use. There is simply no reason that has anything to do with UEFI or Secure Boot.

    The point is that MS is NOT requiring that OEMs should have Secure Boost disabled. On the contrary, the state of Secure Boot is OPTIONAL for W10. Besides, these requirements are only to be able to get logo "Designed for Windows 10", which does not mean that other PCs cannot run Windows 10. Just as this was not the case with Windows 8, by the way...

    First, that's referring to "after-market", which means the computer did not originally come with the card and you are replacing either onboard video or a different card.

    Second, that article is 2 years old, and probably refers to cards that are much older.. every card I've used from the last 3 years has been UEFI compatible. But... if, for some reason, you have a brand new system with Windows 10, you may not be able to upgrade the firmware of a 3 or 4 year old video card. You can always plug it into a different computer and do the firmware update there. Or, you might have to get a new card.. it's not completely unheard of for old hardware to be incompatible with new hardware.

    Either way, this is probably a very rare scenario in the future.

    im not sure about the low end cards in the 7xx series but i know the gtx 750 and higher can be installed without the need to disable uefi boot.

    i think it would be best to wait until more info is release before having a big discussion about this, im about 95% sure you will not need secure boot to use windows 10, as most of the comps running windows 10 will not have a uefi bios.

    Very good find @Winuser.
    I found out the hard way. Been there, Done that. I almost took my first video card back because I thought it was defective. I decided to check the internet first and I'm glad I did. I bricked my first video card by trying to flash the bios to UEFI.

    It's not that you need UEFI to run Windows 10. MS is going to allow the OEMs to do away with the option to turn off secure boot. Or at least that's the way I understand it.
