Running a 4690K with a 1080ti and gaming at 3440x1440 at the moment.
I'm really torn, as I think my primary bottleneck is that I'm running 'only' 8GB of memory. But DDR3 really is a dead end to throw money at, and may not resolve my main gripe of lengthy freezes during shootouts in The Division 2.
Buying an all new CPU (probably a 3600), motherboard, memory and potentially PSU will be a vastly bigger chunk of change but is likely to last me another 5 years.
I've been watching a lot of reviews and keeping up with these forum threads hoping for that eureka moment that pushes me into a purchase - Come on SandVywellBridge owners, inspire me!
I am on a 4690k with 8GB of memory and I experience no freezes during shootouts however I am only at 1080 with a 970. I am not sure if the higher res would be the cause of your problems.
