CPU - as I just mentioned in the thread on performance, you can’t completely ignore GPU performance. You don’t need a monster GPU like a 3080, but with a decent CPU, a 1650 will become the bottleneck at 1440p. I’d suggest a minimum of 1660 Super, and with a top performing current CPU it might even need more than that to prevent the GPU being the bottleneck. Also, while some claim the game runs on one core, I have found this varies depending on unknown factors. I have seen the game using multiple cores. If I set the affinity before running Steam to limit the game to a single core, it runs terribly. Nonetheless, you may well be correct that a high clock speed 4 core CPU is better than a lower clock speed 6 core CPU. The turbo speed is probably more relevant than the base speed.
AMD vs Intel - there won’t be many people who can answer this. I can tell you my Ryzen 5 3600 PC scores considerably higher than my i7 6700T PC. It’s the difference between it always being smooth vs having visibly unsmooth animation even in heavy single player use. It will probably run better on the latest Intel CPUs that are >5GHz than the Ryzen 3x00 CPUs, but the Ryzen 5x00 CPUs might take the lead.
RAM - I just had a look and I’m seeing the game using 4GB during the benchmark with 6GB commit size. 8GB is in general tight for a gaming PC, but if you only want to play this game, it might just be adequate.
1440p gives a much nicer view of the map IMO, but some people are happy with what you can see at 1080p. You can get the 1440p map view on a 1080p screen using the method I described in this thread:
It’s claimed in an earlier post in this thread that the game is capped at 60fps - this is not true. Proof:
