PowerColor doesn't usually make the most rock solid of cards and I am boycotting them for their Swastika theme that used on one of their coolers.
Sapphire has traditionally made some of the best ATI/AMD cards on the market but avoid buying ANY card that uses SMD mounted ferrite shielded inductors.
MSI and Asus are safe bets for the 7850 as they have a much higher build quality than most and have great cooling.
Thank you for the response. I looked at that Sapphire card again but did not see mention of this smd mounted ferrite shielded inductors your speak of. Did you notice that just from the pictures? I do like the fact that it has dual fans and I have also heard what you say that Sapphire has a great reputation.
