Easy line rate if you crank the MTU all the way to 9000 :D

If you're using the boost algorithm rather than a static overclock, and when that boost is thermally limited rather than current limited. With a good cooler it's not too hard to always have thermal headroom.

In my experience jumbo frames provide at best an improvement of about 20% in rare cases, such as ping-pong UDP protocols such as TFTP or Citrix PVS streaming.
