Did anyone upgrade their wireless card?

[LodenCorp]

Which wireless card should I get? I see the ultimate 6300 or advanced 6200 but they add 18 to 36 dollars. Is it worth it?
What upgrades are necessary? I know the screen is, it should be a HD+ for T510

I got the 6300 for the triantenna capability:
More speed at further ranges or better signal reception at similar ranges compared to other wireless cards.
A little more wouldn't hurt at this point.
