The jump in picture quality from standard definition to 1080P was huge. Based on my viewing of the Sony 84" 4K TV, the jump from 1080P is very small, unless you get closer than normal viewing distance. When I got about 9 feet away from that 84" 4K TV, it absolutely looked like a 1080P signal. If you plan on sitting less than 3 or 4 feet from an 84" screen then yes, you definitely need 4K.
