I already have a rig that runs the gtx 660 in a Phenom X2 560 with 8g of ram in an antec 300 with stock power supply and a 1080p 60hz ViewSonic Monitor. I want to get an RX480 in the future and be able to upgrade the processor if needed then, but for now i think that the G4400 will be enough upgrade for cheap.

Sorry if my English isn't perfect.
