Open source drivers don't support GPGPU.

Won't work
New Xorg doesn't support flgrx etc.
Kernel module also unsupported afaik

The support has become much better I think, if I understand correctly at least.

The old proprietary driver, Catalyst (fglrx), is no longer recommended and effectively deprecated. Old and recent cards are well supported by the open-source driver, Radeon (xserver-xorg-video-radeon).

The very latest cards are supported by the new free driver AMDGPU (amdgpu), with the possible addition of the proprietary component AMDGPU-PRO (amdgpu-pro). This would probably be what you should research before buying your card: make sure that the model you choose has the feature you talk about, and that the Linux version of the AMDGPU(-PRO?) driver supports it.

Does that support GPGPU?

I don't know, that's why I said that you should research that before buying. If it does, it could be on certain cards only. At least I provided you the pointer - I think that new free/proprietary driver might be your best bet, not fglrx or xserver-xorg-video-radeon (that I personally use for a fairly old GPU).

Thanks, I'll read about amdgpu.
