The Sapphire HD5870 is a excellent card, the pinnacle of gaming performance for enthusiasts available today. The Vapor-X cooler does a great job of not only being more effective that the already impressive reference design, but more compact and quieter as well. The factory overclock while modest helps bump up performance to even higher levels at lower temperatures. Being shorter than the reference HD5870 is another plus point - anything to help these newest generation monsters fit in your case is a good thing.
The inclusion of not one but two major games is a great added value, especially the hotly anticipated DirectX 11 title DIRT 2. The included peripherals are pretty standard, but nice to have - although I can't really imagine anyone using the card with a PSU without at least one 2x3pin PCIe power connector, they might be very useful for when adding a second card.
Rage3D awards the Sapphire HD5870 Vapor-X five stars! The Vapor-X offers top performance, unique style and outstanding cooling which delivers excellent value - definitely worth the premium over reference designs. More of the same please, Sapphire.
