Then I would recommend the a6-5400k out of those. It's got quite a bit better graphics than the 5300, and should run almost most games at 720p and older less demanding ones at 1080p. The cpu part of the intel's will be better, but they won't do much gaming at all. But for day to day stuff all of them should be more than fine.
Try to get as fast ram as you can. You can usually get 1600mhz and sometimes even 1866mhz for about the same price as 1333mhz. It will mean better graphics. Make sure you get 2 sticks regardless of which speed you get. Given that it's a k processor, it's also unlocked which allows you to overclock it. You won't get a grand overclock with a stock cooler, but you can get a little bit more performance out of it.
