The R5 would be the better of the options you could look at.
If the price range is about $200 for cpu, the R5 1500 or R5 1600 would be a good fit.
I went with the R7-1700 and have been very impressed with it overall. The performance boost over my 8320 has been huge. I do CAD and 3d environment renders, streaming, and just general gaming (GTA5 and FO4). Both went from an average of 30-50 fps to above 60(well above but I my monitor is set to 60hz). When i turn vsync off, I'm usually in the 80-90fps on the same video settings if not better.
