Summary: Got this card as second Radeon HD 5870 card to use in crossfire configuration. Paired together provides very good gameplay experience even compared to modern graphics cards in terms of FPS and picture quality. Fan could be loud at the time of full load, but virtually silent when idle.
Summary: Works well as advertised, email support is very good. The fan is way too noisy at full power. I prefer those hamster-wheel fans some of the cards of this class have. If you can afford it and can install such things, get the Arctic Accelero Xtreme cooler for it. Those are quiet, light and cool much better than stock fans. If you want to mine Bitcoin with it, it's too slow now. Even 5970's are mining slow now that Bitcoin is more popular.
Summary: I love these cards i have two of the in crossfire x and they are amazing. ok the only problem i have with them is heat ill say it again HEAT!!! ok there not as hot as the new nvidia cards but they run a little hot not to hot but the fact that there right next to each other means the top card doesn't get as much air if only i could find a longer crossfire bridge it wouldn't be a problem.
