I'd recommend saving up and not even getting anything... the 6300 is good but you'll look for something more down the road. I'd wait until you can get an i5 and an R9 280x+ or GTX 960+ setup with a nice PSU and MoBo. Though, if you are eager to upgrade I'd recommend getting a new CPU and MoBo kit (atleast an i3 or 8320, there price/performance is just spot on) You can always use your old PSU and Case so a $200-$300 upgrade wouldn't hurt the wallet that much
