Which one of these Wireless PCIE cards are better?

[redsn0]

Hello,
I have come down to 2 wireless networking cards, I cant decide which one to get.
Before you reply, no, Ethernet is not an option for me.

Also, money isnt a problem.

Please let me know which card would be better.
I am upstairs, and my router is downstairs. My macbook gets 50-60 mbps, where as my pc, gets 15mbps with an old dell adapter, which is half broken.

Which will be better for me?
Also, will it get me around 50mbps speeds?

The rosewill in my opinion, it's two times faster pretty much

Depends if the router is N600 or higher. If its slower then the Rosewill will only go to whatever speed the router supports
