It depends on your budget really. Pairing a 760 with a i5 4670k/4690k is pretty stupid. A friend made me and a few other friends do this 2-3ish years ago when we know nothing of computers. He really screwed us over, he got everything wrong.
Anyway, the 760 & the corsair VS series are outdated and no longer sold I believe. Where did you find a 760 for sale? The PSU is fine, it's good enough. Case is fine too.
What's your budget? 800-900$? What about a hdd and ssd?
First, pick a graphics card, a 290x or a 970 and build a system around that.
