If someone here tries to recommend you MSI, I study in a college where everyone has a heavy workload laptop, and all the msi users have faced the mother board problem due to excessive heating. It took 3+ months of replacement time.
I would instead recommend, Asus TUF series or Lenovo Legion 5i Series. I personally use a Lenovo and it has the best thermal systems. Or browse more model in these companies as well. I would not recommend dell at any cost but, you can go for HP Omen series ( Not pavallion please). I have hands on experience with these devices, so you can trust me.
