AMD Radeon 290

[Baho Utot]

I am looking to upgrade my graphics card from a Radeon HD6770 to an AMD 
290.  This work station dual boots
FreeBSD 10.1-RELEASE-p10 #0: Wed May 13 06:54:13 UTC 2015 
root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
and win7.   This will be for email, web browsing etc,  no 3D rendering 
required.

I have looked at https://wiki.freebsd.org/Graphics and it states that 
the card is not supported.

Is any one currently using an AMD R9 series graphics card?

If so can you give my some feedback on upgrading to an AMD R9?

What works/doesn't work etc

Thanks
