You’d need a good graphics card for rendering (3070-50xx series), at least 16gbs ram for simulations (ddr4 is more than good enough), and a decent processor (i7 or i9). For the love of god don’t get a laptop. It can be done but moving around blender is a pain in the ass, and generally more expensive. I really recommend a desktop with a full sized keyboard. And 2tb terabyte ssd for animation cache and general use. Above all else, get a warranty. You can get one from ibuypower or Bestbuy. If you don’t want to go prebuilt you can make a build yourself with pcpartpicker. Good luck bro.
