How well does Crossfire work?

[TopWargamer]

I currently have an Asus DirectCU R9-290 and I was wondering if it would be worth it to buy another 290 for Crossfire. I'm just worried about how well Crossfire will work on games. The only games I'm playing right now are Fallout 4, Final Fantasy 3 and 14, Audiosurf, and ya, that's pretty much it for now. I know Crossfire would only be worth it for Fallout 4 from that list, haha. So ya, how well does Crossfire work, and for the games that it doesn't really work with, can I disable it without having to remove the card?

FO4 doesnt support crossfire or sli natively

you would have to enable it manually

but usually 90%+ increase in the FPS

Fallout 4 is easy to run so you wouldn't actually be utilizing it, unless you plan to run games at ultra @ 144Hz or Ultrawide 1440p.

It depends on the game, but normally you get better scaling than on SLI'd Nvidia cards.

Doesn't matter if you have 980ti SLI or Titan X Sli, they all bow down to the "Shadow distance" settings in Fallout 4.

Why not both?

micro stuttering still exists, unfortunately

correction,

how well does a given game support crossfire.

it varies, but in most games you will see anywhere from 70-80% increase to performance

I actually meant to put a and/or there.

Why not both?

 

Really though, since you already have one 290 I'd say its worth it 

Crossfire is generally supported or can be manually setup, and you usually see slightly less than double the performance scaling in most games

I'd say challenge accepted, but I don't own Fallout 4 so I can't test it.
