so I own the Vizio and could probably sell it for about 700 bucks which would allow me to afford the new 4k tv. My question is which will have the better picture overall. Obviously the 4k tv will have better resolution but what about color and refresh rate. The vizio packs a seemingly useless 480hz refresh rate while the 4k tv packs 120hz. Will this matter much if at all? Basically what would you do. Keep the 55 inch 3d tv or get the 50 inch 4k tv.
