Yes. Many new CPU chips have some sort of integrated graphics processing unit, but it's best used for very casual home use like streaming Netflix or looking at your aunt's vacation photo album on Facebook. To launch the most popular game titles, you need a dedicated GPU, but it doesn't have to be a fancy, expensive one. You can use an older card like a GTX 1650 or Radeon RX 5500 and still get a lot of mileage out of your build.
