"You might wonder why we'd bother looking at the reference GTX 570 when we've already had a look at an option from Gainward which carried with it both an overclock and a new cooler. Well, the reason is simple - While the Gainward card is good, it doesn't offer the truest form of GTX 570, as it's got a bigger cooler, an overclock and a higher price tag. What it ends up doing is skewing everything for us and it makes it a little difficult to tell you exactly how one model compares directly against it.
So with the MSI reference design on offer, which is still the most popular design a month and a bit on since launch, we'll see how exactly the GTX 570 sits in our TPR and TVR graphs, while also seeing how it compares to other reference card offerings from AMD and NVIDIA."
