Only 1,6 and 11 are non overlapping. Channel 3 overlaps with 1 and 6 in the 22MHz range. Odds are you can get a AC router and it being newer than what is around should work fine for you until everyone around you goes to AC. 5GHz uses different channels.
You should also conduct your speed tests when wired. Wifi always results in less bandwidth due to its packet overhead. If you find you are not getting 75/75 with a wired connection its time to call your isp and have them do a line and modem check.

The AC router should arrive today. I am on channel 3 right now because channels 1, 6 and 11 are totally filled with at least 6 other routers in range on each of those specific channels. At least with channel 3, even if there is overlap, I have the center of the range for the entire channel to myself right now. My understanding was that the signal was kind of like a bell curve, being strongest on the frequency that corresponds to the channel it is set to and then overlapping the adjacent 2 channels on either side as the signal tailed off.
The wired connection is showing 75/75 always. The wireless connection varies widely from as low as 10/10 to a max of about 30/30 on any one device. The biggest problems are with watching video over the wireless or connected to my work VPN. Because the bandwidth fluctuates so dramatically over even short periods of time the videos arent always fully buffered and the VPN is not reliable.

make sure to get AC usb adapters to take advantage of the AC bandwidth
if you look at the first 2.4ghz graph you will see channel 3 over laps channel 1 by 50% and overlaps channel 6 by 33%
This is why everyone tries to use the nonoverlapping channels 1, 6 and 11 of course if they are too close to you then it causes contention.
Does sound like the wifi on your present router is having issues considering those posted rates. Getting a new router is a step in the right direction I think
