Having had a quick glance, most of those seem to be at 1080p. Not where I have noticed bottlenecks or where the OP is interested in gaming (has 1080p height but wider width).
They use 1080p as it's more CPU bound then higher resolutions. The lower the resolution the more the CPU has to work.
It matters to the OP because it shows that his CPU is fine and there will be no difference upgrading it. His resolution is higher than 1080p.
I envy the back plates on the G1
its worth it just to see it idling at 27°c
