Im looking to trade my PS4 for a mid-low range gaming pc. Does this pc that is being offered have capabilties to run games now at low-medium settings? And are there upgrade capbailities? It has a 550W power supply. A MSI A78M-E35 motherboard. AMD A8 5600k APU. A LG disk drive. A 1 terabyte segate hard drive. And one 4gb geil Evo stick of ram. I don't have any OS installed on it.
