Let's see...
Samsung 840 PRO is what you want.
1KW PSU is massive overkill for a single card, even the 780. A quality 550W PSU will handle a 780 and an overclocked haswell quite easily.
2x4GB for a gaming rig is also plenty of ram.
So, it looks ok, but you can save a few bucks and still have a more than awesome gaming machine (suggestions I listed are money savers that do NOT affect FPS).
