Havent heard of this stutter issue. What clocks have you hit with that awesome VTX card of yours?
loljustlol
I have not experienced this stutter issue that the 680's are plagued with. I would be interested to see if any other 680 owners have this?

If you're dropping 10c by taking the side panel off then your case cooling must be pretty poor.
reading some reviews when overclocked the 7970,680 and 670 are neck and neck and as much of a amd fanboi as i am i have to say the 670 looks to be the card of the moment, even when you look at the gtx 690 the gtx 670 sli looks to be a much better cheaper option

I think the real enthusiasts card will be the GK110.
I hope so. I will be interested if it allows for big boy overclocking.
Dave, what do you get in Heaven at 1150/1650?
and is your 2600k OC'd at all?
I'd agree that the 680/670/7970 are all pretty much even.
Something definately not right, there mine at 1250/1600 (1275mv) was not going over 62C with fan at around59%
It'll do 1170/1600 on default voltage and sure it will go higher if I upped it a little.
There is a 23 page thread over at the nvidia forums all about it. Basically if you are running 60hz and enable vsync it drops frames and stutters. Nvidia have known this for about a month and are yet able to provide a fix. Could be driver related or even worse hardware. I play racing games and like the game to be as smooth as possible but the constant judder forced me to move on. Shame really as it is a nice card.

Fair play. I suppose it is hardware mixes messing something up. I just have never seen it is all and after coming from a 560TI, this is so smooth and no judders anywhere.

Not run it at that frequency even though it's my daily OC, only at v high clocks, and yes my i7 is overclocked to 5ghz for benches.
Agree about the 680 and 7970 being the same, but the 670, hmm, when overclocked they could start to show faults assoc with lower binned GK104's???
Shouldn't do. It's just the extra GPU Cores that the 680 has. It doesn't seem to make much difference for a lot of games with the clocks much more important. Infact with the lower number of cores and full size PCB's etc on non-reference cards they're practically the same thing.
Regarding some of the issues with boost frequencies mentioned on the first page, the GTX 670s boost speed has been increased to around +200 MHz:
- Reference clocked 670s boost to 1083 MHz
- 980 base clock (models like the gigabyte windforce) boost to 1189 MHz
- 1006 base clock models like the KFA2 EX OC, and an upcoming Zotac boost to 1215 Mhz.
