Getting a firmware update without a 4K TV is pointless. There will be games with the FPS unlocked, but the 10,000 point differential is not justified. Only about 3-5 games worth playing will appear noticeably better on a 4K TV; optimized games will look same. After investing in the necessary firmware, I started to consider building a dedicated gaming computer. A custom-built gaming PC can be built for under $30,000 if you don't have Sonya. No, you won't get 60 fps on ultra, but Sonya's 4 hardware is still old, and you can get better performance and cheaper games on Steam with a PC for the same price (30k). Take a fatka for 11,000 on eBay, buy more games on disk, and resell them for the same price. This works for exclusives. The only case in which upgrading makes sense is if you already have 4K and are feeling a really severe itch in your wallet with money is if you have fat or slender.
