Considering HDMI is a digital signal, it really doesn't matter how far away you are, it will either work or it won't. There is a small bit of wiggle room in there, but for the most part the whole distance between sources is an analog signal issue. There are still maximum cable lengths with digital signals, but there's basically no quality loss as long as you're within that range. The drawback is as I already said, things either work or they don't, unlike analog signals where there was a significant amount of "in between".
Companies make an absolute killing on selling cables to people who don't know that there's really no difference between some $5 HDMI cable and that $80 cable you list. Further, HDMI is HDMI, so there's no point paying extra because some company put PS3 in the name and paid Sony for the privilege of putting the PS3 logo on the packaging. Don't waste your time on things like Monster's gold plated HDMI cables or whatever else, because it will have absolutely no impact beyond maybe extending the maximum cable length a little by lowering the resistance of the cable on the signal.
Just go to some place like Monoprice and get yourself a cheap HDMI cable. It'd also be a good idea to educate yourself further on the differences between digital and analog signals. Let other people pay 10-20X more than they need to for a cable believing it will be somehow beneficial.
Overall, I subscribe to the belief that as long as you're only 6 feet away from a console or cable box you don't need to spend big bucks on an HDMI cable. However, I am experiencing issues with my new television (Panasonic 55" Plasma Viera) and it was suggested that an official Sony HDMI cable could be a good fix. Has anyone had an experience with this happening? Here are two cables available by Best Buy:
<div>1. Sony Official HDMI Cable 6.5' - $49
2. Rocketfish PS3 HDMI Cable 8' - $80
I don't mind buying one or both since I can just return them, but would you recommend one over the other or do you think it is just malarky?
