I see that several makers of the ATI radeon 5000 series consists of different manufacturers ( like sapphire, gigabyte, msi) and i was wondering which company is it better to buy it from for best performance?

I would go for Sapphire they been with ATI the longest but really it doesn't matter much just look at the warranty info.
