Would i notice a difference in using any of the following wifi cards? My build is the following:

My internet service is Time Warner Cable's extreme (up to 30Mbps)

Most importantly, what am i getting for the additional money spent with the more expensive cards?

Is there a better card for my money than any of these cards? Also if i were to upgrade my internet service in the future would i need to get a better card then any of these?

As always thank you for your advice Tom's Hardware!

Any of those will work.

The 'speed' on those WiFi cards is for your internal LAN speed, not talking to the outside world via TW.
Unless you live in an area with Google Fiber (gigabit fiber) on the horizon, that will be fine for quite a while.
