On the performance side of things the Gainward GTX 570 1280MB Phantom doesn't really offer us anything new. The slight overclock when compared to a reference card gives us slightly more performance than a reference one.
Where the card really shines is in the cooling department, and to be honest that's a good thing since that's no doubt where the focus is for the new Phantom series. While noise levels weren't all that much lower than cards we've seen before, including the GLH version from Gainward, where the card does shine is in the heat department.
We saw it comes in 4c cooler than the Gainward GLH card which is louder, but the 11c drop compared to the reference cooler is indeed what manages to stand out on the model. Combine that with the little overclock on offer which helps boost performance a little and you've got a great card on hand.
The biggest down fall to the card is that it's a 2.5 slot card which essentially makes it three slots, as you can't do anything with half a slot. For most people, though, as we mentioned it's not going to be an issue, but it's indeed something that you need to note if you do have a lot of expansion cards or you're thinking about getting two and you don't have more than one slot between your PCI-E slots.
Apart from that small issue, though, that as we said won't affect a lot of people anyway, this is a really nice card. More importantly, though, it looks like it's going to be a really nice series and with Gainward already attacking the GTX 580 and GTX 560 Ti with it, they must think they're also on to something.
If you're looking for a GTX 570 that runs nice and cool and is whisper quiet when idling away in Windows, the new Phantom model from Gainward is going to be a good choice.
