I have one like the second type. Tried to run a gpu under Linux with it , didn't work. Think I ran into an issue with Linux and this being the 4th Gpu in the system. Gave up pretty easily to be fair. Been meaning to have another go at getting it to work successfully as a lot of people use them for Bitcoin mining, so we should be able to use them too.
The best form of help from above is a sniper on the rooftop....
