No, the 3D driver bounty ends two generations before the oldest fully OS4-supported PCIe GPUs, as I told you half a year ago:

It won't add any new Radeon chips, just add 3D drivers for cards already 2D-supported currently. Or has the bounty goal changed meanwhile?
As to "latest", even OS4 is 4 generations behind by now.

More like a daughterboard ;-)

I'm afraid Bigfoot's upcoming 3D drivers won't change this.
