I was looking at the Sager NP8130 and there is an option to upgrade the wireless network card. Is it worth it to upgrade any of these? How much better will the laptop perform with the upgrade?

Here are the upgrade options:

Built-in 802.11 Wireless B/G/N - Stock Wireless Card + Bluetooth
Intel® Advanced-N 6230 - 802.11A/B/G/N Wireless LAN Module +
Bluetooth ( + 25 )
Intel® Ultimate-N 6300 - 802.11A/B/G/N Wireless LAN Module ( + 35 )
Bigfoot Networks Killerâ„¢ Wireless-N 1102 ( + 40 )

Not unless you have a specific need for drivers under a different OS. They'll all perform very close to one another.

The Killer card has a built in quality of service module. With the right drivers, it will sift through time-dependent traffic and set a higher priority.

Or you could just set up qos on your router.
