Connecting my PC to TV using a long HDMI Cable

Hello, my PC sits in the living room with 30 ft between it and the TV. What is the best Best way to connect it to the TV so that I can set back and game? A long HDMI cable? My graphics card is HD5870 infinity version, so it has only display port and i gotta use a converter to connect it with hdmi.

Thanks

Wireless HDMI?

I did something similar. In my house there is a crawl space and the coaxial cable comes out of the floor. I have an Ethernet run similarly to my computer so all i had to do was widen the holes in the little cover thing. Not if sure if you have the same situation at your house but it seems like a wireless solution would have too much latency to game.
