Thank you in advance

You are saying you already have a built in Intel AGN card, correct? At least that is what the driver is for. Why do you feel the need to get a different wireless card, and possibly one that is worse? From what I understand the one you have installed in your laptop already is fine, if not a better performing card than any USB variant. The one in your laptop is using antenna's that are build into your monitor, which would be far more sensitive than ones that are limited to a USB stick. If you want to upgrade your wireless card, look into minipci cards, which will replace the one you have. However, a warning, you will probably not find one all that much better than what you already have and replacing one is not easy if you have never opened up your laptop before. Getting to the card can be hard if it is not already behind an externally accessible cover.
So, to sum up, stick with your currently installed card. Option #4.

so polorboy i guess you checked whether or not the Advanced-N 6200 AGN chipset has patched drivers that will inject? If you are using backtrack 4 it would seem that you are or want to be a penetration tester and at some point in time you might want to inject packets into a wireless router. Also since Backtrack 4 is a linux OS linux drivers have to be used with the chipset as well. So last time I checked the offensive security website was still referring people to the alfa as the go to usb device for BT4 and pen testing. Also since it has a sma connection you can add a higher gain antenna for more range. Hell i built a biquad from a satellite dish and have it connected to my alfa. Unless the OP has their own N router that they are going to use at home, don't get the NH model, its a pain in the ass with the drivers, the regular b/g model AWUS036H is plug and play with Backtrack 4 and the patched drivers that come with the live cd and the vmware image also inject very reliably.
plus if you do ever want to run BT$ or some other flavor of linux as a vmware image you can't put any on board wireless into monitor mode, so usb is the way to go.
