Crossfire RX 470 & 480 worth it?

Would it be worth it to get a 480 or higher to crossfire with my 470 or would it just bottleneck the higher end card?
 
Solution
In most cases it would limit the faster card to the capabilities of the lesser card. However, if you used the RX480 / RX580 as the primary and disabled crossfire on titles that don't support it, you would then have that level of performance.

Really though it is best to get a single faster GPU. Sell your RX470 while the value is still higher than normal, and pick up the fastest card you can afford. (Also buying an RX480 or RX580 is practically impossible for reasonable sums right now)

You can't crossfire a rx 480 with a rx 470. Also crossfire has even worse support than sli which has next to no games that support it.

Multi gpu is almost dead for games so no worth investing in it.

You can crossfire RX470, RX480, RX570, and RX580, they are all the same GPU. Crossfire and SLI are definitely on the downturn for newer titles, though. Next to no games is not correct though. When considering it, you just have to look at your titles and see if they are supported.

 


Let me restate it a bit better. Most of the ones that do have sli/crossfire support have it badly implemented (next to no gain in performance or in some cases even loss of performance).

I disagree. I used SLI with both my GTX580 and GTX980 and most mainstream games were indeed supported. (And games that didn't tended to run fine on a single card) I only switched to a single 1080 because it simplified power consumption and Unreal said they weren't going to support AFR at the engine level. Since so many games that I tend toward are Unreal based, it made sense for me to make that investment.

(Unreal Tournament, Mechwarrior 5, pugb, Gears of War 4, Warhammer, and a few other popular titles) But according to the lists below, all the games that are used as standard benchmarks are pretty much supported.

Not an endorsement, a single GPU is always better, just that until very recently, the only way to really go beyond 1440p with AMD was to use older cards in Crossfire, such as R9-390x and Fury cards. RX 400 and 500 series just never made sense.
 
I use SLI and it is supported in just about every AAA game. Sometimes not right at launch, but all of the AAA titles get the treatment. Some games scale better than others and you will never get 100%.

The games that don't get SLI support are typically indie games that don't require demanding hardware to begin with.

Crossfire is the same way.
