Summary: The 5870 has some of the best performance numbers in its generation. I needed one of these to set up a Bitcoin mining rig and the numbers you get from this are just great for the price. I used this in an Ubuntu Linux machine and the drivers work like a charm. I highly recommend these!
Excellent video card. Uses less power, runs cooler

Summary: I bought 2 of these in October 2010. They are excellent, and virtually silent. When I tax them the fan speeds up and they consume more power, but they are still quiet compared to many cards. They stay cooler with the Vapor-X technology, and are stable. Two thumbs up!
Summary: I am able to play games like GTA4, Starcraft2, Company of Heroes, Crysis Warhead, GRAW2, and many others on the highest settings on 1920x1080 and have minimal to no lag. Even under load this video card is very quiet.
