Which wireless card for gaming?

[DonNagual]

I have the following options for my notebook.

Wireless 802.11 g/n

Intel® Advanced N + WiMAX 6250 a/g/n 2x2 MIMO Technology (extra $50)

Killer™ Wireless-N 1103 a/g/n 3x3 MIMO for Gaming & Video (extra $80)

is it necessary to upgrade if I plan on gaming?
