if you buy a new Radeon and plan on using it for gaming, then check the clock&ram speeds with powerstrip when you get it. There are apparently plenty of people who have received cards set at diferent speeds. This issue existed with the previous radeon releases as well. In one statement given to Hardocp.com from ATI they basicly said that they give no gurantees as to which clock speeds will be on your card. Strange sounding, when frames per second is a product of these speeds. But apparently that is their position. I believe the new retail Radeons are supposed to be clocked at 270 core and 270 DDR.
By the way, I am not referring to differeces in OEM and retail versions. I can come to terms with that. What angers me is that ATI's position is to not list clock speeds as a spec and let the consumer gamble.
Also, boards "Manufactured by ATI" will say exactly that on the outside of the box. This leads many to believe that other companies will be making ATI boards.
FYI, I've seen 7191 drivers out there.
