Gaming PC wireless card: use old-school PCI?

I set up a gaming PC for a friend, but I forgot to get a wireless card for it.

It's a Z68 motherboard with enough PCIe gen2 slots to hold 2 spanking video cards. I'm assuming that in order to keep the PCIe interface clear for the video card throughput, I should get a wireless card that will install in one of the old-fashioned regular PCI slots.

Is this right? Thanks in advance for any help.

 

or a USB one. Belkin do a really nice MicroUSB one that you can hardly see.

 

Patriot also offers a USB WiFi "N" card that's dirt cheap (less than $20) and very reliable. I've sold several in the past few months at my shop, they have a strong signal and require no driver setup w/ Win 7:

Hope this helps.

 

I agree with the "dongle" option and several to choose from a N150-300 will allow for the future.
