Crossfire with 380x worthwhile?

[PandaParadox]

I know there are a couple threads about this, however my situation is somewhat different, I recieved a 380x as a gift for a job I did. Not only can I not return it because the 30 days are over, but I wouldn't want to sadden the gift giver.

Since I was looking to upgrade from a 270x (Which I gave to my girlfriend) this card came right on time. However, I'd like to get just a little more power from my PC. That being said, would crossfire be worthwhile? It's my understanding that any other R9 can be crossfired (meaning I don't necessarily need another 380x).

I am running:
cpu: fx8320 OCed to 4.7
mobo: GA-990FX-gaming from Gigabyte
PSU: EVGA SuperNOVA 750 G2 80+ Gold
GPU: Sapphire R9 380x NITRO

It can only be crossfired to another of the same architecture, in this case tonga, so should be crossfireable with the r9 285, r9 380 and r9 380x.

I wouldnt bother personally, I would put the money into upgrading to an intel platform.

I do not believe the 200 series is compatible with the 300 series gpus. So in the end I do not believe you can Crossfire those cards.

If you could, I believe one card is slowed to the slowest card in your crossfire so you will get the equivalent of 2 270x GPUs.

There are some debates on this however. Read this...

If it works let us know, because I am curious.

Rob beat me to it. 😛

No, the 270x is not the same GPU as the 380x and you can't crossfire them. You can Crossfire a 285 with a 380 and that's it. There is no 2-series equivalent to a 380x so the only card you can Crossfire one with is a 380x.

It is sometimes possible but not supported to crossfire two cards with similar GPU models if one is a cut-down version of the other. The 270x and 380x are totally different designs so this is not possible at all.

380x should be able to crossfire with the 380.

380x's in crossfire will perform at a Fury X/980ti lvl. Crossfire/sli has some issues though... some game are not supported as well.

He said he gave his 270X away to his girlfriend... He didn't ask about crossfiring wth a 270X.

True he did not say that he was going to use a 270x, just that he was not married to a second 380x. So as long as he keeps the GPUs in the family of the 300s then he should be fine.

I missed understood the post on first read too. Thanks for correcting us, SMB.

AMD's site specifcally states that only a 380x can be crossfired to a 380x, which means that if it does happen to work it's not supported. As I mentioned above.

Can you link to that? Usually cards of the same type can crossfire. Like the 7950 could crossfire with the 7970/280/280x
