Up Close
A graphics card without a fantasy figure on the front. Saints be praised. The Zotac black and yellow colour scheme always looks classy and here it's nice and minimalist. After all, with such a beast inside the box, why waste excitement on the outside?
The card itself is well protected in the dense foam and heavy cardboard combination.
As well as the adaptors for power and display we have the Zotac bundle of games and drivers. If you haven't tried Trackmania it's worth a punt and you get three days with the Zotac card.
Here it is in all its glory. We get so used to cards with red trim on them that we really like the yellow Zotac scheme. Not only does it make a nice change but we think it looks better.
Otherwise the card is the same as we saw on the stock model, with nVidia green branding on the side and a dark PCB.
Outputs remain the same two, there is an HDMI, two DVIs and the DisplayPort.

Now, where can I steal a pair of these cards form
SWeet review TTL. Thx.
Yep. 7970 seems a bit cooler, but a bit noisy (stock). The only difference between 680 is that AMD has no any useful/useless features like 680 has. Still I see no reasons for fanboy pee-war.

If the 7970 is louder but cooler and the 680 is quieter but warmer, cant you just spin down the fan speed on the 7970 and have it quite and warmer just like the 680? |
Or- you can spin up the 680 fan, to make it as noisy and cool as 7970 does
Just like Intel Speed Step
if the 680 has more headroom it overclocks higher(single thread apps), if it is loaded down (all cores active) it doesn't boost .
Somewhere there will be a line where a slight OC will let it boost to the max TDP, but pushing the OC just a few MHz more would cause the 680 to not boost at all, cutting performance.
Overclocking video cards just got harder, now you have to actually find a balance over your entire spectrum of applications and workloads instead of just find the highest stable MHz, because you could be cheating yourself out a bit of performance.
From Toms SLI videos the pair of 680s were never really at 100%, so they boost all they can, whatever Tom raises the base frequency, they still boost higher.
With a single card, it's workload is higher, so it doesn't boost as much, if at all.
The figures I wrote down from my OCing on air:
Kombustor DX11 default clocks = 216min, 229 average.
+175core/+500vram = 247min, 266 average.
That difference is enough to make gameplay smoother on BF3 ultra on the most demanding 64 player map: Damavand Peak.
Yes, agree, if the clocks are pushed too far it can actually reduce performance but it's so easy overclocking and you quickly establish what too far is using Kombustor Dx11 mode (gives you immediate feedback of the min, max, average).
It's also important to use the EVGA OC scanner to check for artifacts. Although I had the vram at 650mhz, artifacts show past 500mhz.
Have been as high as 247+ on the gpu core.
