If you were connecting to two different routers and had a balancer then maybe. Its not worth the effort. If you got a low wifi signal then get a repeater :D

I am plagued by the slow downloading speed of my wireless connection to the internet. Since it is not an option to hardwire my pc, I decided to see if I can benefit by purchasing a new adapter. I am using www.speedtest.net to test the download speed on my pc using asus wireless adapters. When I use just one N13 (older Asus) I get around 2-7 mbps. When I use the newer N53 (new Asus) I get around 4-7 mbps. When I use them both, I get 6-13 mbps. I could be wrong, only relying on speedtest.net results, but it is helping. Now, I was told at the computer store that I cannot use two wireless adapters. But I am not seeing any troubles so far. It is just so much faster now.

Unless you want redundancy it's pretty useless

Yes, you can have multiple wired or wireless network connections but, in my experience with Windows 8.1, you have to connect manually the second wifi network each time the PC restart. By the way, for the others posters, I don't see why is relevant what he/she is trying to accomplish. Maybe is just for the sake of curiosity. But if you wonder, there useful scenarios like:
1) One connection for internet and the other for sharing files in a private (isolated) network.
2) One network adapter for a virtual machine and other network adapter for the host (without sharing the bandwidth).
3) One internet connection for downloading torrents (using binding) and another connection for browsing (modifying metrics).

Connecting two wireless adapters to the same computer will not improve the system's Internet connection speed. Adding a second Wi-Fi adapter to a computer will improve the Wi-Fi performance if the second adapter features a better-performing standard, but it's overriding the older, slower card, not working in conjunction with it. The Internet connection speed is usually bottlenecked at the service provider level and the Wi-Fi connection has enough bandwidth to support all of the available Internet speed.

Actually I am testing as we speak.
Scenario Home Office with a Personal network and a business network.
One User connects to Business and one to Personal.
That way i can switch back and forth, also it allows me to run carbonite without pop ups saying drive not connected.
Just started, minor problems. One internal wifi and one USB adapter.

Back in the day in widows xp you could use multilink protocol to have two nic cards. I tested this once where one nic card transmitted the data and the other was just used as the receiver and I/O was much greater than before. Not sure if windows 7/8 supports this anymore because of how much faster everything is today vs back in the day and removed the ability to do. When a computer has more than one nic card/wifi card it is called a multihomed pc and many times this is not allowed on corporate network. But of course I am sure this is just fine in a home environment.

I will investigate this myself and see if I can use my N WIFI card to transmit and use the second AC wifi card to receive. I am sure it is possible but not sure if my windows 8.1 will allow me to do so. Also I do not think games like world of warcraft would like such a setup as WARDEN might ban you.

I have a Sony Vaio laptop with a Qualcomm card. I added a USB wifi adapter and it seems to be happily using both. I haven't had a chance to test performance difference much yet, but there is no conflict or other problem. Running Win 8.1. Both show connected to internet. Both using same network.
Internet speed is much faster subjectively. I haven't run an actual benchmark, but I am getting page loads and mp3 downloads seem much, much better than what I experienced before without the adapter or with the adapter alone.
