Can someone help me upgrade my pc? I'm uneducated but I have the specs of my gaming pc I bought a while back.

I bought a gaming pc a few years ago and while it is ok, any game I run has to be run at the lowest settings. If it's not too much money to upgrade some parts so that I can run a modern game at medium settings, I'd love to do it and get into pc gaming. Here are the specs specs. If anyone has suggestions on the minimal amount I could put into this that would make it usable, it would be greatly appreciated, thanks. via /r/buildapc http://ift.tt/2sZ4YQc
