I was using the intel card on my laptop before I switched to the Atheros. I'm wondering if anyone has done a comparison on the two devices, my main points I'm looking at are:

Power usage, performance, and overall support for primarily Linux/Unix operating systems. I have both cards with me now, and am hoping to settle on one to use.

In Linux I'm using the ath9k driver and the iwl4965 drivers.

Features provided by both will also help me make my decision, I know madwifi provides a lot of features and functionality but it does not provide N support and it is not free software.

Thanks in advance!
