What are you trying to accomplish?
Usually triple gpu gives you diminishing returns.

What do you mean by diminishing returns. Its a general term. I am doing 4 monitor 1440p setup in portrait. Its weird but I have a big budget.:bounce:

Yes, you can Tri-fire with a 295x2 and any 290x card. It scales pretty well for 4k gaming (jumping from trifire to quadfire is really where the efficiency drops down a lot). Another site did a review of a 295x2/290x setup and they got a sensible increase jumping to the 3rd GPU at that resolution in a lot of games.

As long as your motherboard can support tri-fire, you should be ok. Keep in mind though that (according to AMD) the 295x2 wants 16 lanes of PCIe 3.0 bandwidth, so if adding another card causes you to go to 8x on that slot, you may end up starving your 295x2 a little (this has been debated). This makes sense as it's two GPU's already sharing a 16x slot (just on a single PCB).
