r290 X with r280x

[pnico]

I just upgraded from a 7970 to a xfx 290x whould i see any benefit in adding a second or even adding to 280x ?
I've always had cfx or quad fire and it always seems to be overkill..
I do use Eyefinity but it seems that 1 290x is more than enough powerby itself any thoughts thank you

You can't xfire anything with a 290 but another 290 or 290x. They are fundamentally different architectures.

The upgrade was not necessary and not worth it, the HD7970 is a good card and you cant crossfire a r9 290x with a r9 280x.

I think that's up to the OP to decide. He did mention he runs eyefinity, so the extra performance may definitely be worth it for him.

Crossfire 290x is overkill unless you running 4k, I recently upgraded from SLI GTX 680's myself however I got some mining going on

I just feel having 2 290 X will be an overkill . I have a weird res but do use eyefinity.

My res is 5760 by some thing. I don't recall the other part.

no, putting in a 280x would do nothing as it cant run crossfire with a 290, as has been said, they use different gpu's. not to mention there are problems with stuttering, dropped frames and visual artifacts when crossfire and eyefinity is combined on the rebadge 2xx and 7xxx cards below the 290.
