Since the OP ask for Dolphin , not for multi-tasking . I say against it
Pentium Haswell is i3 haswell without Hyperthreading . Since Dolphin doesn't support Hyperthreading , it's meaning less to get an i3 for Dolphin unless you need extra clock speed (i3 has higher clock speed)
Base on Dolphin Benchmark , i3 4130 beats all AMD CPU in Dolphin (include FX-8350 @ 4.2GHz). If you get FX-8350 and OC to 5.0GHz then it may have a chance to be on par with i3
On AMD side , AMD 760K (Athlon) Richland is A10/A8 6xxxk Richland without Integrated GPU , Athlon has lower clock speed
