I don't know. Previous release integrated most of the big improvement.
This one has software skinning that should help games with skinning. I have found in my quick test that Tron is gone from "complete slideshow" to "not bad, but too slow to play" at 50% speed. So, may be it will help some games, but others (like Ridge Racer 2 for example), just play the same.
Also, I haven't noticed any significant improvement on compatibility (for example, for Disidia 012, you still need to remove Buffered rendering if you want to see something). But once I've fixed that file writing issue, you'll see by yourself (a dual core may help, this emu can do multithread things, quadcore, I'm not sure it's usefull). A better/faster GFX can be usefull too.
