Essentially what you can tell from the above explanation of our testing is that changes to the cards have resulted in us moving from synthetic tests such as Furmark to real world testing for power, temperatures and noise, even though the Gainward card uses a traditional power design. The results above are therefore what consumers can expect to see when using these cards themselves.
Looking first at the power use of the GLH card we see that it sits a little above the reference model, quite acceptable for an overclocked edition. The temperatures recorded on the Gainward card are much better than the NVIDIA card though, it knocks 7c off the reference design when gaming. In addition to that the GLH's custom cooler runs quieter than the NVIDIA design which makes it even more desirable than the standard card.
With a custom PCB and cooler we were keen to see how the Gainward GTX 570 GLH would perform in the overclocking test and the answer is very well. There was a decent memory overclock but the increase on our core was most impressive, not far off 200MHz above stock with a small voltage tweak in Afterburner.
