Interested in hear the justification why you would need more than 1GbE in a machine built specificly for gaming.

I bet at least 90% of people buying this connect it to WiFi and never think about connection speed again!

Personally... my internet is only 300 Mbps. My WiFi connection is roughly on par with 1GbE. I have a very small pool of 2.5GbE capable devices, but overall I'm just not fussed about making the switch.
