Hey man! I bought a gaming PC for about $550, with an AMD FX-6300 Six-Core CPU and a Nvidia GeForce GT 730 GPU, and I run most of my games on either high (GTA IV, GTA V, American Truck Sim) or the highest settings (iRacing, Flight Simulator X, Car Mechanic Sim 2015, World of Tanks). The only game I have to run on low with my computer is Beam.NG Drive, but overall it's a nice setup and more wallet-friendly than others. From what I see on Amazon, GT 730s will cost you from around $67-$90, depending on if you go with the 1 or 2GB versions (correct me if I'm wrong but I do believe bigger is better, and I believe MSI has a 4GB card), but it's a decent GPU that will get the job done (at least until I can save the money to upgrade to a GeForce GTX 1050!).
