I'd like to upgrade my computer so I could play computer games at ideally max quality and possibly stream. I already own the case, PSU, and hard drive, but I don't really have a budget and I'd be willing to change anything in this build. Also, on pcpartpicker, it said that the ASRock motherboard has an onboard USB 3.0 header, but the Antec Sonata Elite does not have front panel USB 3.0 ports. Is that something I should be concerned about? Thanks in advance.
