Due to the fact that Gainward gave us such a strong overclock out of the box and the card not being rumored as an overclocking beast like the GTX 460 was, I didn't know what to expect when it came to getting more out of the core.
I was pleasantly surprised, though, to get another 50MHz on the core and 200MHz QDR out of the memory which is made even better with the complete lack of need to add extra voltage to the card.
On a whole the cooler also manages to hold up well and while the card does indeed get a bit warmer and run a little louder when at 850MHz, the levels aren't anything that we'd be worrying about.
As we mentioned in our standalone review on the Gainward GTX 570 GLH; it's hard to know just how the model sits compared to a lot of others because we haven't looked at a reference designed card yet. Still, we don't need to review a reference card to see that when overclocked the Gainward GTX 570 GLH offers us some serious performance at a good price.
Looking at the current lineup of AMD based cards, it's only beaten by dual GPU setups. Come the 15th of December it's indeed going to be very interesting to see what happens as we see both AMD and NVIDIA go at it like we haven't seen for a while.
