7. PCI express 2.1: What an adavantage... Unfortunatly the cards are so slow under Linux due to bad drivers, that they cant take adavantage of a bigger bandwidth. Correct me with TESTS(!!!) if I am wrong.
8. DirectX11: Yeah! What an big advantage under Linux!
So the summary is in reality:
Nice card, nothing new besides the name and some internal stuff no real world linux user would see. If you are a Windows user, check reviews of other sides!
Congratulations for such a nice and really usefull review!
