I want to run league of legends on max settings with 60 fps. I would also like to run things in the background while playing. My budget is 800-1000$ Do monitors have an effect on the tower or can I get any tower. For the specs keep in mind that I'm also looking to stream.
Many models, all the major features are listed on the same page so you can easily compare CPU and video cards.
I'd stick with the upper range of your budget for a gaming laptop. Whatever you get now is what you are stuck with till you replace it. So another $200 spend now means a better system 3 years from now when you want to play some new game.
