Go to micro center to get the 3770k for $230 instead of $300+. Much better deal. Also, the fact that you got a DOA card doesn't mean anything. Usually that's just the vendor's fault. For example I bought a msi 660 ti from newegg and it was DOA, but ordering the same card from amazon it was fine. Not that newegg is a bad company, but apparently amazons version of the packaging was better•
That case is such a waste of money lmao, $160 for a case lolz. but whatever your choice.
But 680 + 3770k will be pretty nice, though a 8350 + 7970 would be much better especially when you started streaming and such.
but whatever, waste your money. Lolz. A $800 build would work just fine, even a $500 one.
