GeForce GTX 760 SLI or GTX 670 SLI?

[bustedup13]

I'm doing a full revamp on my system at the moment, currently have:

Asus Rampage IV Extreme MB
Intel Core i7-3930k OC @ 4.5Ghz stable
16 GB 1600mhz DDR3 (will be upgrading to 32 GB)
One EVGA GTX 760

I have the option to buy two overclocked GTX 670s for $220 each, or I can buy another GTX 760 (currently around $250). My question is, should I buy the 670s and sell the 760, or save the money and get the 760. Is the performance boost really worth the extra almost $200 I would pay? Anyone?

The 760 is the 670, but updated with a higher clock rate.

I would go for the second 760. The fram rates of either sli set will be very high anyway.

that's what someone had told me, but one of my other friends said that was the 770, not the 760. In that case I'll just buy the 760 and call it a day. Thanks for the help.
