Got my set today. Its only like R380 delivery incl so wont be a big @$##$ when its not performing bad. Will test it on my 2x HD3850's and post my findings in the next few days for those that like to know. I got a Gigabyte Chassis thats known for bad curcilation (around the HD's anyway). Maybe I can take out a few 120mm fans. My system sounds like a jet taking off.
