Latest versions are currently the fastest, there's no excuse for old versions.
A 2310M is much better than my Athlon II X2 220, and I currently have no problems with SSBM (except for lag in moments where it doesn't really matter if there's lag anyways), or, really, most other games I have. I have no games currently ripped which I cannot run with the current version of Dolphin, which is impressive because I have most of my personal library and a tiny bit of the family library ripped, and am using a CPU that was completely hopeless around a year ago.
