SSD over the WD HDD for me.

PSU is not very good. You can get inexpensive units which are pretty good.

Honestly, it depends on your budget, if you can spend the extra money, get yourself a 1060 3GB atleast, prices are coming down as new things are being released and it would be a good edition to your PC. Also, an SSD is a very good investment these days, it will really breathe more life into your system and speed things up. RAM could be upgraded, but its not too necessary, maybe when you save up more you can upgrade to 16GB.
