Going to get straight to the point, had to retype this on a phone screen . Anyhow I need to know a good gpu that will not bottleneck my amd fx-6300. Also only have a 500watt psu. Please try to make sure it doesn't bottleneck, and it also will be used for minecraft with shaders and fallout 4. Also please list the alternative amd/nvidia card. Such as a gtx 960 would equal an amd r9 290, but make sure to tell me what one you would prefer. Thanks! Sorry for the vague details, had to retype this twice now because I lost wi-if connection at my house, then it made me retype everything.
