Feels like want to upgrade over my existing S8+. The new camera, 12GB RAM and 4500mAH battery is tempting. But the 1440p at 60hz is a let down...sigh. At least make it 90 hz ma.

I can't answer that question for you cause neither of us uses it to play games. I do play cod mobile but I do it on my iPad. Tbh I don't see any difference from my time when I was using the SME version.  Wife seems to be satisfied with it. If gaming is your main focus then Samsung isn't the way to go. You have much better choices with better gaming functions like the the ROG. Which I've used as well but other than its gaming capabilities, I didnt see anything special and great about it.

My opinion is you won't know the difference until you start nitpicking on benchmark scores and reading in too much on what people say about Snapdragon and exynos. I only bought mine because my wife needed a new phone and I loved the ultra. So instead of getting the Exynos version I might as well try the Snapdragon version of it. And no, I don't see the difference from my day to day use.

But hey it's your money. Do what you want with it man.
