I'd really like to do some light gaming on this but I don't have a ton of money to spend, so try and keep it under or as close as possible to $500, please. OS not included. Also, no peripherals except for the monitor. Hope to be able to run Overwatch and Spellbreak on this at somewhere close to 50-60 fps. I don't really have a preference on what brand you use, as long as it stays under budget. Located in the U.S. Thanks!
