Is Crossfire worth it?

[Sir Lags A Lot]

So if you might can tell by my recent activity, I've been wanting to upgrade my gpu. I've asked a lot of topics about it as well. But I just got the idea of running crossfire. Now doing it with 2 Rx 580 8gbs would be pricey. But I had the idea of running two rx 570's. I saw a video testing them in crossfire and according to it, they beat the 1070. But I have heard disadvantages of crossfire and multi gpu solutions. I haven't done any multi gpu setups in my life so I'm wondering if it would be worth it. And I think it would be cool to have two gpu's running at the same time.

I have 650w corsair psu. Ark, fallout, farming sim, and gmod are usually what I play a lot.

From what I know, Ark is not multi-GPU friendly.

Farming Simulator and GMod does not support Crossfire / SLI.

For you use-case, better to go with a single powerful GPU instead.

 

Running Crossfire / SLI on lower-end GPUs is not worth it -- hence why even the GTX 1060 does not support SLI.

RX-580 would be okay, but would not recommend running Crossfire with anything below that.

You're already aware of some of the drawbacks with multi-GPU configurations, so I won't bore you with it.

Ok, seems like I wouldn't. Ill probably go for a single 580 or 1060.

waste of money only a few games utilize crossfire and SLI and it barely makes a difference

What about a rx590 ?

as a crossfire user from the ati x1600 days till today, no, I would not recommend AMD crossfire at all.

I will list the game that should run on AMD crossfire,

fallout 4, has profile and is supported, real world, it crashes all the time, within ten minutes usually.

far cry 3, has profile and is supported, real world, its crashes all the time, within ten minutes usually.

GTA 5, does not have profile and is supported, runs great on my crossfire.

BF 1, after waiting a year,it has a profile and is supported, this now runs fine.

dx9 titles like HL2 and its mod games seem to run well.

having brought enough gpu power to that of two times a game that would run on an xbox 1 or ps4, I found this option to be bad.

I would look at the 3d mark scores for the hardware to make a decision on what to buy, you can find information on what two cards would work like compared to a single card in the same price range. a good fast cpu is needed to gain real performance.

most modern titles like fallout 76 and post scrotum which I have purchased seem to not support and run badly on my rig. the latter being something I find offensive to be selling.

 

I only wrote this as I was looking for info on why crossfire is not working with fallout 4.

In General: Multi GPU setups are for shits and giggles, not daily driver!

Because they just don't work too well and often have some really huge Problems.

One is for example the fact that it just doesn't work with many modern games and its just a hassle.

Might want to take a look at VEGA 56.

If you are lucky you might get one for like 310€ or so + Shipping.

I've seen one of those a couple of days ago.

CF support has always been very game dependent. Although looking at the big picture things have definitely improved, they are still nowhere near ideal and it took a LONG time to even see this much improvement. Single GPU is still the way to go for guaranteed performance.
