If you run a single gpu on the 4k monitor, does it lower your fps significantly? Or is it the same FPS as with 2? 4k monitors are quite advanced and can really destroy FPS on certain gpus, even very good ones.

Ah I thought you meant that when you upgraded from a different monitor and a single gpu you are getting the same fps. Do you have a crossfire cable across the gpus? (I'd assume so). I don't have that type of gpu, meaning I don't know how to enable crossfire if you have to.

There isn't anywhere for the crossfire cable to do

You need a crossfire cable across the gpus for both to work. That would explain only one of them working. I would look up a tutorial on how to install it on youtube.

There is no Crossfire Bridge with AMD's newer GPU's. Open the Catalyst Control Center and Enable Crossfire. Also what motherboard do you have?

That board does support Crossfire, please be aware that the top PCI-Express slot is version 3.0 running at 16x, and the second PCI-Express 16x slot is 2.0 running at 4x, so the second GPU may not run to it's full potential but it will help.

In Catalyst Control Center under Gaming there should be a CrossFire X option.

Happens some of their newer GPU's have them and some do not so it is easily confusing.

A motherboard that has a PCI-Express 2.0 8x slot for the secondary slot, or two PCI-Express 3.0 8x slots. You would have to look into the specs on the motherboard details.

That being said enable CrossFireX and if you are satisified with that then you are good, you can also use GPU-Z to monitor the usage of both GPU's so you can find out when the PCI-Express 2.0 4x slot is limiting your gaming.

Do you have the latest version of your AMD drivers? That board is supported for CrossFire.
