I currently have an AMD A8 6500 with 8570D Int. with 6GB RAM and a 200W PSU (I believe). I want to be able to play Titan Fall, maybe GTA IV, NFS: Shift (1&2) and game that are similar to those. I have looked at GTX 750 Ti and an R7 265. My current setup can play titan fall but not all too well. I dont wanna spend anymore than $150 on a GPU as I might need a new PSU and need to fix my car. Thanks
