First off, I dont need you guys to tell me to spend more on a gpu. I don't want to have to buy a new power supply that works with a Dell Inspiron 570. I also paid $80 for the computer, monitor, and accessories. It has a good CPU (AMD Athlon II X2 3.0ghz), and 4gb of ram. My goal is to be able to play 4k YouTube videos smoothly, and to get high fps on Minecraft, and maybe play a couple other games. Is the GeForce GT 610 1gb my best bet? ALL help is appreciated! Thanks!
