Question Integrated graphics for gaming ?

[noob-but-not-rud3]

1) Are integrated graphics worth it ?
2) Which one should I get ? AMD or Intel ?
3) Should I use stock cooler or get a better one?
4) Are there any heat issues?
5) Does performance drop after a long hours of gaming ?

Im not that knowledgeable in P.C.
I mainly play Dota 2 , Counter Strike 2 , and Valorant.

Will it be possible to get 80fps(average) in CS2

Thanks
