I am looking to upgrade my PC now that its around 5 years old. My parts are listed below, but I am unsure what I should upgrade. I am looking to do some gaming, mostly overwatch and apex. I would also like to add a 1tb hard drive to provide extra space ontop of my ssd. I get about 30-60 frames in overwatch at epic settings with frequent frame drops. I'm looking to spend $300-$500, what parts should I buy?
