We used PerformanceTest 6.1 by PassMark which you can find out more information about here. It has a handy Advanced Networking section which is perfect for our testing.
Doing our best to emulate a real-world performance scenario, I setup a server running Windows 2008 R2 (x64) Server, (2x Xeon Quad Core 3.0 GHz 1333MHz FSB, 4GB DDR2 FB-DIMMS, 2x 146GB SAS drives in RAID 1) and the client PC was an MSI Wind 200 With built-in Intel 802.11n (Intel WiFi Link 5100 AGN) adapter. The results were gathered by sending data from the MSI netbook to the server at different distances with the built in adapter, a TPLink TL-WN821N and then a TRENDnet TEW-644UB adapter. Average transmission speeds were recorded for each.
* As we did not have any network adapters that support the full 450Mbps yet, we did our best with the adapters we had on hand. If you can find it, the Intel 5300 wireless chip does support this new speed and is being integrated in newer laptops.
Our connection speeds were around what we expected them to be. With the Intel WiFi we had connection speeds of 135Mbps. Now, with the TRENDnet TEW-664UB we saw these skyrocket to 270Mbps as you can see below.
Of course, this connection speed did not seem to convey as far as actual speed goes.

Our testing shows that while the speed on the TEW-691GR is good, it is not too much better than the typical n series router. At least it won't be until we see the next generation of adapters hit the market in larger concentrations.
Our gaming and media testing showed that the TEW-691GR is excellent for media transfer and streaming, but it is not exactly the greatest at gaming. After testing three popular online games we found it to only be average in terms of ping and response. Although this was disappointing, we are also pretty sure this is due to the adapters we used, not fully supporting the full speed of the TEW-691GR. We do hope that we can get the Intel 5300 adapter or another adapter that supports the full 450Mbps soon so that we can test the full gaming potential of the TEW-691GR.
