Hmm, good info. Something is wrong with the link you posted by the way. Looks like there might be a NBSP at the end of the URL for some reason.
So, the technicals were a bit over my head but if I understood correctly the max speed using google fiber would be 500Mbps (500Mbps between the router and google, then another 500 Mbps between the router and the client), right?
I'm assuming the POE and Lite do not suffer from this?
