I would say just buy a better video card and see what that does for you.
Why buy a an entire new board and CPU? CPU/MB does NOT matter that much.
8 Gig of RAM is probably plenty as well.
500 g SSD and 1 TB HD? What does a normal HD cost now?probably not much.
If you are planning on upgrading everything, why not just start with one thing at a time and see what that does for you.
So for you, upgrade video card.
