If you're seriously planning on OC'ing your CPU in the future you can stick with the i5 4690k, but otherwise you're probably better off with an i5 4460 or something similar. You also wouldn't need an aftermarket CPU fan since the stock one would be fine.

Aside from that, I would keep an eye out to see if you could find maybe a 650W PSU for cheaper. I didn't find one after a quick search, but even with an AMD card you shouldn't need 750W.
