Hey everyone, it's been a while since I've been here. I built this pc years ago when my needs were very different. Now, I am wanting to see if I can put a video card in it that will allow it to run Overwatch. Being able to run other games would be a bonus. I imagine I would need to update the power supply, so looking for suggestions on that too. Would I be able to slap a RX 580 in here and be okay, or would I need something older/more specific? Video cards have never been my forte. The build list is below. Thank you in advance.
