780m SLI vs 680m SLI

I have seen a lot of people comparing these two and some people swear the 680s are better where others disagree - so what's the truth here? Can someone break it down for me?

My experience of 680 was just that it ran so hot that I was nervous to run a consistent/daily OC. That was in a Sager NP9370.

 

680m Hot? It shouldn't, it should run sub 70C at stock clocks. 780m will run much hotter, and draw more power, but you also get the performance benefit. I think if with good cooling and proper power supply, 680m OC'd and 780m OC'd would be within 10% of each other.

 

Yea, I am pretty sure I got a dud. In another thread I was explaining to someone when I had first gotten my 680m build that the primary card was running like up around 84 - I tried literally everything a man could try. Even got a new heatsink, I think it was just a bad chip but that was my experience!

I have no problems with my 780 build though. The kid that bought my 680 build was just trying to buy my new one for an "upgrade" and wanted to trade me that machine back plus cash - being a family man and the fact that has a 120hz screen...it is tempting.

How could one get better cooling on a np9370? I did all the normal tricks.

 

My 9370 with 680sli ran 84 one main card and 78-80 on the second card. I now have a AW 17 and a AW 18. My 17 has a 780 and actually played bf4 about 10 hours today and it peaked at 69. My aw 18 running bf4 peaks at 74 main and 70 slave. This is all with stock dell paste. So I have had good luck so far with the 780's running cooler than my 680's did in my sager.
