I'm planning on upgrading my internet before I do a new gaming pc build, and I was looking into some more high end routers. I want the ultimate performance and it seems that the top choices are ac1750, n900, and ac1900. I'll have to be honest, that I don't know anything about the difference with routers, they all seem the same to me. But I want one with both 2.4 and 5GHz frequencies, and high in mb/s speed. Cost doesn't mater much to me. If someone could help me understand the difference between ac1750, n900, and ac1900, and which one would be best for gaming it would be much appreciated.
