What's the difference between these two 802.11b/g/n wireless adapters?

Quick question:

What's the difference between these two wireless adapters? Obviously one is PCIe and one is PCI, but I don't know why one would be better than the other. I can't decide which to get.

This is my motherboard: ASRock Z68 Extreme3 Gen3
I also have an i5-2500K and a Gigabyte Radeon HD 6950.

Here's the PCI adapter: Rosewill RNX-N300 Wireless N Adapter IEEE 802.11b/g/n PCI

and here's the PCIe: Rosewill RNX-N180PCe Wireless Adapter IEEE 802.11b/g/n

PCIe can transfer at a much higher speed, but it's unlikely you will be able to max out the transfer speed of the PCI card in the first place.

Both have the same specs wifi wise, it will really come down to which slots you have free.
Your motherboard has a PCIe 1x slot above and below the top PCIe 2x slot. the PCIe 1x ones are the smaller slots.
Normal PCI slot above and below the lower PCIe 2x slot.

I'd go for the PCIe, cheaper and smaller. Should fit in the slot above your graphics card.

That's good enough for me! Thanks for the help. I almost spent $5 for nothing!
