The results we got from the GTX 470 when it came to overclocking was very interesting. To be honest, we wonder if NVIDIA held back the power of the GTX 470 a little because they couldn't get the power out of the GTX 480.
The question now is what kind of overclock can we achieve out of the card with the fan on auto and what voltage is safe? - We did a bit of testing at around 75% on the fan and we didn't really have any noticeable issues at the same presets as we used in our graphs. Honestly, by dropping the voltage a little and the clocks slightly you could probably get similar performance with the fan on auto.
What really makes this exciting, though, is wondering what the potential of the model is when we see companies attack it with new coolers. We're sure that MSI are hard at work on doing something new while Galaxy and Palit both have non-reference models coming out.
With a better cooler we might be able to get even more performance with the card, suppressing the performance of the GTX 480.
MSI as usual have done a fantastic job of making a card so much more valuable. Looking at our TVR you can see with this massive overclock it's the best valued card to date that we've tested.
No doubt we'll be looking at Afterburner again when we start to see some GTX 400 series cards that move away from the reference cooler. For now, though, Afterburner has added another dimension of performance which is fantastic.
