So I just ordered my Sony 47" W series, and I need a good recommendation for some HDMI cables. I remember reading in here or somewhere else I should never pay more than $20. I walked by a guy who worked for Comcast and he told me the freebies they give out are just really cheap ones rated for 60hz, and I should get nicer $20 one rated for 120hz if I'm using it with a Gaming PC, and I might notice a difference. I asked a few other different people and they both said the same thing. I asked a Sony Rep, he said the same thing. I asked him where he's getting his information and he said independent research, not what Best Buy tells him to say. So what HDMI cables are these guys talking about, and this this a real thing? What should I buy and from where? The TV will be ready for pickup on Sunday so I really need to get moving on this ASAP. I didn't think I'd be buying the TV this soon and wasn't prepared.
