I'm afraid I'll have to wait for Sapphire's Vapor-X solution to come out. The stock design is over 60 DBa. I don't think I'll be able to tolerate that regardless of the performance. I know Sapphire doesn't have a lifetime warranty like XFX but I had their vapor-x 4890 briefly and it was really QUIET. Anyone have the same noise concerns or do you just plan to slap on an aftermarket cooler to get your stock 5870 to tolerable noise levels?
