I'm torn between the 65" Samsung KS8000 and the 70" Vizio M70. My sofa is 10 feet from the TV and I plan mostly on gaming and watching movies with this TV. I have a PS4 Pro so I'd like to take advantage of 4k gaming, but it's not critical. The 70" seems like a nice size, but I think I'm trading off a lot of performance if I go that route since I'd like 4k to be as good as possible on a budget under $2,000. Which one would you recommend? Side sofa seats are a bit closer than 10 feet too. Thanks!
