Even a 3600X is rated to boost to only 4.3Ghz so yeah, I think your CPU is running very well. 40% in a game isn't a very heavy workload so I can't say whether 68C is good or bad, especially if it's on the stock Wraithe cooler.He must have a thicc cooler idk what it was but considering mine is 68 on stock with fans running stock. Just to quickly check my cpu is running okay? If its running at 4.2 ghz and like 40% workload on dying light? Also I have the x version
So basically If I get the newly realesed 3070 would that pair well with my r5 3600x?
It's still boosting to 4.4Ghz in the middle of gaming action so that's a good thing. If the CPU starts getting into the high 70's/low 80's it will reduce boosting as Ryzen is designed to - probably to 4.0-4.1GhZ range but hard to say. That will only happen working a much heavier load than the game you're playing and I can't say if a 3070 will move the bottleneck back to the CPU that far or not. The best way to keep it boosting as high as it can is to get it much better aftermarket cooling.
But from what I've read a 3600X is still a sweet spot (balance of price and performance) for gaming even with a 3080 so long as you don't prefer low-resolution, ultra high refresh gaming for super high FPS. Even then it won't compromise gaming action to any noticeable extent.
