I would probably go for an AMD set up with your budget. (also used the same shop as potis)
8320 + gigabyte 970 mobo

The intel would perform better in games like WoW and other CPU bound games. In GPU bound games you will probably not see a difference.
Just putting the AMD option out there due to your budget this way you will have some money left, so you can start saving for a gpu.
