If you are more interested in quick wireless networking than you are in upgrading to a 10Gbps wired network then perhaps this review over at The Tech Report will catch your fancy.  It is similar in design and size to the RT-AC68U, at 6.2×8.6×3.2" but it hides some upgrades inside.  The processor has been upgraded to a dual core Broadcom BCM4709C0 running at 1.4 GHz and the internal memory has been doubled to 256MB though the radio remains the same with rated transfers of 600 Mbps on the 2.4 GHz band and 1300 Mbps on the 5GHz band.  Testing showed some improvements compared to the previous model when it came to range and broadcasting through obstacles, with some increase in transfer speeds as well.  Check it out here.

"Asus' RT-AC1900P carries on the legacy of the company's popular RT-N66U "Dark Knight" router. This time around, the unit comes armed with an 802.11ac radio for faster performance on the 5GHz band. We fired up this router in our crowded wireless airspace to see whether it can stand above the rest."
