You sound like me. I'm actually still considering picking up the 82-inch q90 because it has the dedicated dimming chip. The dimming was my only real problem with the q900.
I was honestly not truly sold on 8K and have no problem sticking with plain old 4K 🙂
Please don't misunderstand, it looked very nice but I brought three people in to compare the two televisions and two out of three preferred the 4k TV.
The guy that picked the Samsung couldn't quit drooling over the 8K factor lol. He's been anticipating 8k for a while now and even admitted that just knowing it was 8K may have swayed his decision.
Look forward to hearing which way you decide to go.
