In my own order of preference for AMD based graphics cards, I'd prefer Sapphire, ASUS, MSI and XFX followed by the rest of the pack including HIS. In reality, they are probably all similar in the quality of components used and the real difference to be found will be in the areas of warranty, quality control during assembly and cooling system design.
So long as you get a card without any kind of manufacturing defect, they are probably all fairly decent.
Go to Newegg and find the candidates.
Filter on the reviews by verified buyers.
Then look at what percent of the reviews have zero or one eggs indicating some sort of a problem.
In particular, look at the reasons for a bad review. Some are not very valid, so exclude those.
