So after more tests, it ranges between 48Mb and 68Mb which is a HUGE improvement over the 17Mb I kept getting on my old router.
The main reason I got this particular model at Costco was:
1. It was Netgear so the same brand as the highly touted Nighthawk which gave me some expectation of similar performance
2. It was on sale, regularly $140 but it was $15 off.
3. The other one they had was the Linksys AC1750 and while faster, for $160, it was only $40 away from a Nighthawk and $35 more than the AC1450.
Like most technology, I usually only get bleeding edge if my need is there and since the Nighthawk is obviously for larger homes (per Netgear's site), this unit should suffice. I'm not a gamer so the bandwidth is really only for Netflix since that seems to chew up the pipe whenever someone is using it. I don't have any Wifi gear set up outdoor so I'm really only concerned with indoor range/signal strength.
I've been trying to read more about beamforming as it seems that the clients also have to support it and since I'm only on the 2.4ghz channel, I'm not even sure if beamforming is being utilized. Whether that's the reason why I'm getting such an improvement is a mystery to me, all I know is it's faster and I didn't have to spend $200 on a Nighthawk.
