I tried SLI a couple years ago and all I got was a slight bump in performance with GPU utilization being low on both cards. There is a reason you see AMD and nvidia both appearing to distance themselves from multiple GPU's. The vast majority of games really don't take advantage of more GPU's... the ONLY game I ever saw a significant performance boost from running multiple GPU's was first person shooters. There it makes sense.

MMO's are notoriously bad for multiple GPU configurations.

Your best bet, as stated by so many, is simply to buy the fastest single GPU you can afford.

Also keep in mind that ESO is pretty CPU bound meaning you really can benefit more with regards to frame rates if you can get a super faster CPU. Intel generally is the better way to go for single CPU performance as they tend to clock much higher especially if you are into overclocking.

I have tried crossfire with eso and it doesn’t seem to be supported by the game. Also, crossfire isn’t always going to give you gains in performance it highly depends how the cards are utilized by the game. Some methods render all the even frames on one card and the odd frames on other which would give better frames per second but will not give you better graphical appearance. Other methods make the cards both render the same frame but different aspects of it, allowing for better graphical appearance but not increased frame rates. Then there are rendering methods that try to blend the two together so there are some gains in both graphical appearance and frame rates.

As the others have said just use one card because crossfire’s performance largely depends on the game developer setting up the rendering engine for it. And seeing most people are not running multi gpu setups they do not spend the money developing support for them. Also, some of the crossfire game profiles don’t even do anything, they just turn crossfire off so that it doesn’t impact the game.

I just heard crossfire is officially supported.

Anyhow, will running everything high on one RX 480 be ok?

There are threads on this forum which describe which setting that work best. In general use set water reflection to low, shadow to high (ultra only make shadows larger) and adjust LoD to what you need to see things in time. There aren't much to gain to have everything set to high or even ultra.

Also, try out Votans Adpative Settings. It can dynamically change your settings on the fly as your FPS goes higher and lower. I just started using it about 2 weeks ago and would highly recommend.

edit: Also if you go into usersetting.txt, changing your High_Resolution_Shadows to "0" uses less resources and frankly looks better. Shadows are almost always rather fuzzy on the edges and not crisp and sharp.

You can also use Votan's Advanced Setting to do that. (lol, I am not affiliated with the guy in any way, they are just solid addons)

What I've heard about SLI isn't so great with this game. I've upgraded the video card a couple times but the single biggest performance boost I've seen happened after switching from a seven year old i5 processor / motherboard to an AMD threadripper. The first trial went silky smooth on ultra settings. Stuttering & input lag is basically gone now with the exception of crowded capital cities, I'm still using the same video card since those prices are still high.
