id like to know which between those two choices are better for my needs id be gaming more if that helps however i dont know if i should sacrifice the cpu or the gpu for better gaming performance
Honestly it depends... the main questions are:
1: What resolution are you playing at?
2: What refresh rate are you targeting?
3: What type of games will you be playing mainly?
For example:
If you are playing at higher resolutions (e.g. 1440p or 4k) and you are looking at 60+ fps target, then you would be better getting more gpu power - the 2700 + 2060 combo would typically be your best options.
If however you want to play 1080p high refresh rate, and you are after 'competitive' frame rates in games like CS:GO and so on, then you would be better off with more cpu grunt so the 3600 + 1660 Super would give better results.
