gtx 670 vs gtx 680

Solution
Yeah 680 and 670 are very close, they both have the same 256bit memory bus, so its purely the additional cuda cores of the 680.

A 680 is easily overclocked to gtx 770 specs. 670s can get close too.

At stock speeds the 670 is often compared to the 760, but once overclocked the 670 is superior, especially if it has Hynix or Samsung vram.
Given a GPU with roughly 88% of its CUDA cores enabled and slightly lower clock rates, I expected the GeForce GTX 670 to give up at least 12% of its performance compared to GeForce GTX 680. But then when they were tested; factoring in the complexities of GPU Boost and add on the fact that frame rates often don’t scale based on shader resources—particularly when an application isn’t bound by shader through put.

Knowing all of that, it is still surprising to see the GeForce GTX 670 sample perform just 4.5% slower than the r GeForce GTX 680—certainly less of a gap than was expect. Knowing that overclocking on air is often enough to overcome a sub-5% spread, this almost negates any reason you might have had for buying a GeForce GTX 680, particularly if you are looking to play games at 1920x1080 with the eye candy cranked up.

We figured that upping the comparison to 2560x1600 would increase the gap between GeForce GTX 670 and 680. But the average is only 1% higher. The 670 still looks mighty juicy.

OVERALL, what you should get from this is that the extra cost for the 680 just doesn't worth it. It would be more cost efficient to get the 670 and continue saving some money and make a massive upgrade in the future for rg , gtx 780 ti etc
 
I love all these GTX 670 threads! The problem with GTX 680 is cost is ~ = to an OC'd 770(there are so many to choose from still).

I'm selling a GTX 670 for $150 because of what other owners seems to be asking for. GTX 680 at the lowest is $280 so 670 continues to be a value leader and has been since launch.

In less the cost is the same or close on the two you should not be paying +$100 more for the 680 vs. 670 (I have no idea what cards/prices you are looking at).
