not a problem at all. my 270/270x cards show as r9-200 series.
the 7950 is similar to the other 79** cards except for clock speed and other options. kind of like the 30 different ford mustang models. they are all mustangs and identified as such but the options will change which model it is (lx, gt, cobra, .......) same goes for gpu's. the chip is the same but the options determine what "model" it is. windows simply stops with identifying the gpu not the options.
