Ah, my bad I buy my stuff from newegg and that is where I got my pricing 960 is $200 while the r9 285 is $200 as well. If you could get an hd 7950 probably has to be used now for the same price range I would go with that instead. As I said that 128 bit bus would no doubt have some sort of impact on how much AA and higher resolution you can do. I will look around and see if someone is using a 960 for dolphin and if that impacts then on what they can do.
*edit After researching the 960 should be fine and it would be a good pair with the pentium cpu. With an oc on that cpu around 4+ghz which you should be able to do at stock volts you will have a great machine for running dolphin. I believe you should be all set and shouldn't worry about much. I am sure you aren't planning on making a 4k gaming machine so at 1080p and probably in 1440p for dolphin you should be fine.
