i posted this over at Mac rumors and got this response! Please see the question posed by the other user below and let me know if this EFI will work in a 2006 Mac Pro and be properly flashed out of the box.

I said:

I want to install El Cap on a 2006 Mac Pro 1,1. I did a bunch of research but could not find my answer.

I need to upgrade the graphics card from the 512mhz card so El Cap can run. I plan on using this machine to make some 1080p videos in Premier for clients. It had 16gb Ram and the original Xeon dual core processors. Can it do the job?

Anyways, I am looking at an AMD Radeon 280X on eBay. It is good priced and pulled from a 2010 Mac Pro.

Would it already be flashed for my 2006 MacPro. I really don’t want to flash a card on my own. See it here;

This Mac was basically free for a friend. Please help!

Response was:

For non 4K display, this card should work. However, you still better check Netkas forum, make sure this Mac EFI can work properly on the 2006. There may be some issue because of 32bit vs 64bit. You should able to found something at there.

PLEASE HELP. I don’t want to waste my money if it won’t work properly!

No you didn't  Wink,5619.0.html,7515.0.html

I can tell you that EFI for 7950 (same is used for 7970, R9 280 and 280X) works with MacPro 1,1/2,1 (you gotta have 10.8.5 or higher OS) but i really don't know how is that particular card flashed or how does it work. The guy is describing MSI card with Powercolor pictures... Go figure.

Always look for Tahiti card with the dual to switch by crossfire port.

Takes all the risk out.

Before asking a question, check your "Personal Settings" and be sure that you have "Brain Services" set to "On".
