I've got a HP Envy 1534 that I purchased new about a year ago. It has no modifications done to it as I really have no clue when it comes to computers. I recently got into Arma 3 and I'm looking to run at higher graphics settings while still getting good FPS. Can anyone tell me what the best upgrade to the computer would be? I'm guessing the graphics card but I don't know that for sure and I don't want to waste money on something I don't need. My budget is limited. Thank you in advance for your help.
