Interesting thought. There are no Quadro drivers in Linux, there are just Linux drivers which work across the entire range.
Still, a lot of those benchmarks weren't graphics related, but benchmarks like zipping large numbers of small files I would expect Linux to win from faster OS calls, better filesystems and caching than Windows. I wonder if they have the same benchmarks for a quad core setup, usually you only get Windows 10 benchies on Phoronix for gaming to show how badly the porting layer hurts.
