Where to find my driver ersion for GPU? openSUSE 13.2

hi, i want to know wich driver is using my GPU and if there is some new driver or somethink like Catalyst where can i set up a little more things then just a resolution and refresh rate.
my GPU is Radeon HD 3650 AGP and desktop OS is:
Linux 3.16.7-21-default

openSUSE 13.2 (Harlequin) (i586) KDE 4.14.9

thanks to everyone for help

I’m uncertain about AMD GPU’s but I believe that AMD no longer supports that hardware (Radeon HD 3650 AGP) So you must be happy with the Open Source driver (radeon) or upgrade the card.

My reading says AMD now only supports 5450 cards up

Yes and the free Radeon-Driver, who supports that Card, is working better for every Kernel-Version…
