I am looking for a new receiver to go hdmi with. I have a ps3 to play movies with and some gaming. I am looking at the onkyo 705 or the sony 4300es. Can some one advice on which one I should buy? Is the sony worth the extra $200? I also am just looking at a denon receiver. I want to spend no more then 800. I have 71 series samsung tv if that matters. Thanks
