It seems that a lot of GPU problems revolve around specific versions of drivers. Though AMD has their own support structure, you can often learn from information reported by others who fold.
The GPUs.txt file uses the device ID to identify a GPU. The description field is often based on the first information available when AMD-ATI releases a new GPU. However, AMD-ATI often reuses a device ID for a number of different GPU's based on the same chip, so the description may need to be updated to reflect that. But it does not affect the actual folding, the capabilities used to assign GPU projects are based on the device ID detected.
There is more information about the GPUs.txt file available here - viewtopic.php?f=83&t=26208. The type of information requested there for requesting a GPU be added would be more useful than a screenshot.
