Sure, upgrade is fine.
What I mean is that at 1440p the workload goes more to the videocard, relieving the cpu. So would you have a faster videocard with that 3770k, you would be above 100fps no matter the settings, under 1440p.
1080p relies more on the cpu but in my case still brought me around 100fps with dx12, and between 70 and 90 in dx11. So fps wise it didn’t change much going from 1080p to 1440p.
But I agree on your upgrade wish. Have fun picking the parts.
ps. too much cpu is always fine, it will last longer. Just as my 2600k lasted for 8 years, and still played bfv fine.
16 threads do help. And in the near future we will see consoles going 8 cores/16 threads also. Games will be programmed to use that, so on pc we are gonna need that also.
