Redhat Linux 8 gfx card prob

hi guys,

i have just installed Redhat Linux 8 on my home computer and it doesn't have the valid driver for my Radeon 9800 xt have looked about for it and can't find the driver.

My computer works fine in a way, i can use it, but it would just be nice to have it set up fully correct so i can get the extra functionality out of the gfx card if i am able to under Linux!

cheers in advance

Mark
