Is there any difference between GeForce GTX 760 and 770?

A couple of days ago i stumble upon something amazing. I was building my custom PC and I'was searching for wright graphic card for my SLI configuration. First of all I didn't have enough money for GTX TITAN because a $2000 for a two cards is too much. I wanted to buy two GTX 770. Then i looked into specification of GTX 760 TI and 770. And I noticed that they are practically the same. For example look at these two pictures below.

Product Name  :	Gainward GeForce® GTX 760 2GB
Barcode  :	426018336-3002

Memory Clockspeed  :	3004 MHz (DDR6008)
Pixels per clock (peak)  :	N/A
Bandwidth  :	192.3 GB/s
Ramdac  :	400 MHz

I took these tables from Gainward site. As you can see both graphic cards have 2048 MB of GDDR5 memory. The first difference is in Power connector's which means that the GTX 760 will need less juice A.K.A. power to run. The second difference is in Bandwidth.

So, in conclusion the GTX 760 is practically the same card as GTX 770 and it is more power efficient.
