Go for the R9 380 over the 960, it's cheaper and better, just make sure to get the 4GB one.
That SSD isn't great as Kingston pulled a bait and switch with the controller or something so it's no longer a good SSD.

Also went with a 650W PSU for potential future additional GPUs and cos it was only a fiver more than the 550W one.
MSI's "PC Mate" mobos aren't the best so I switched it for this one.
