Good rig, although I would swap out the SSD for at least a Samsung EVO or the M550.
1) That motherboard is fine, or an ASRock Z87 Extreme4. Overclocking is not necessary if you're gaming. Serious emphasis on this.
2) Depends on how much you want to spend. A good starting point would be a Corsair 200r.
3) A 280x is simply a 7970 therefor it's better than the 760 and trades blows with the 770 depending on title.
4) See above.
