It mostly agrees with this - https://www.tomshardware.com/reviews/amd-radeon-rx-570-4gb,5028-16.html
Whenever I play games like rise of tomb raider, cod advanced warfare the temp is about 75-80C without me performing any oc-ing. Is it normal for amd cards or my card is being too heated. I haven't done anything to clocks or fan speeds
Depending on the cooling type of the gpu that may be high or not and the fan speed curve you've got set. For blower style coolers it's kinda normal to go into higher temperatures while open air coolers tend to perform better but that also depends on the chase size. Do you have enough airflow in your case? do you get same temps with side panel off? If it's lower then maybe look at some guides on case air flows or invest into a "better" case.
