Wireless Connection

I've been running v11.0 for a couple of weeks now, just trying to see if this is what I'm looking for, and I love it. I've got it running on a regular PC and I'm wondering if it would be better to buy a wireless card for the PC or get an Apple TV and stream the content from my PC? I can't do a wired connection by the TV, so wireless is my best bet. Any thoughts or recommendations?

Thanks.
