If I understand the theory and application of it here correctly, such a GPU-Z screenshot is in fact, impossible to have displayed legitimately.
Each driver contains the IDs of the new graphics unit to identify itself, which GPU-Z would recognize it on and then an entry in GPU-Z is manually entered by the developer and there we go, a new version each card with the correct and capable information. So firstly, the driver that it clearly states to be running on does not
have an ID for a Titan LE. Secondly, GPU-Z wouldn't know what to display for half that data even if it knew the ID (reason why with legit screenshots of pre-release cards in GPU-Z we have a lot of ??? in place of info) at the version also clearly shown as 0.6.8.
I don't know why people would bother faking it even and going so low
I'm confident that's the method but I didn't program them so I'm not sure, if a person with confirmed knowledge could confirm the above, thumbs up to them.
