TweakTown posted a review on the Sapphire Radeon HD 5870 1GB Graphics Card
For a while we saw a flurry of new NVIDIA cards while ATI kind of sat stagnant. That's stopped now with the release of the new HD 5800 series from the red team. Over the next few months we're going to see plenty of the HD 5870 we have with us today, along with the lower HD 5850 and the higher HD 5870 X2.Sapphire Radeon HD 5870 1GB Graphics Card Review
Not only that, though, we're going to see companies like Sapphire, HIS, GIGABYTE, ASUS and more put their own spin on it, be it an Atomic or Toxic model or Turbo and TOP ones. What we think the HD 5800 series is capable of today is going to be proven wrong with companies giving us even more performance than the stock clocked model we'll be looking at here first up.
