I'm essentially completely lacking in computer knowledge, I really don't know much. I can understand the basics and look things up, but beyond that I'm really not sure. I just picked up a new comp, Lenovo IdeaCentre K230, and I'm looking to upgrade the graphics card for gaming. Looking to spend about 200 bucks, give or take, but I really have no idea which to get. Any help would be greatly appreciated, thanks!
