An oem ATI card is an ATI card made by Sapphirre Inc., they've been making ATI cards for years and years, (on the 9700pro) all the specs are exactly the same, as well as the layout and components, you get the exact same drivers, cables, etc. etc., the only thing you don't get is the snazzy box and paper documentation, who needs another book when it's on the cd and is self expanitory anyway. I have a Sapphirre board and it runs great, btw they also use the same support staff (from time to time) , technical documents, and warranty period.
