Simple Questions - March 06, 2015

So, I think it's time for a new graphics card. I have been running the following build for a little while. Just recently I added the 4k monitor (I know the refresh rate is low), and upgraded the SSD along the way.

Anyway my question is this:
* I've been running this 7870 for a while, and I think it's definite time for a new card.
* I'm running the 4k, as well as a 1080p in portrait mode.
* I don't anticipate running any more monitors, but I'd like to be able to hook 3 up for special occasions. * I want something under the $600 mark, preferable even under $500, but I'm flexible if need be. * I run Linux. Usually Linux Mint, but lately Openbox, just for reliably. I don't intend to do too much gaming on linux, but I often have a 16gb virtual machine running Windows for Photoshop etc, and might even dual boot for some gaming.

Thanks in advance!
