Can't get Radeon HD 7470 to be seen on Ubuntu - help me find replacement?

[puck2]

Code:

VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos XT [Radeon HD 7470/8470 / R5 235/310 OEM]

I'm tired of trying to make this work since it is an old card anyway. Will I have better luck with a newer card? I need smaller form factor card to fit in my PC case.

Any recommendations for cards that will work in a smaller PC case - and will be seen by Ubuntu and Hashcat?
