What should I do with a new in box 390x?

[winningsince1337]

I have been running 290s in Xfire but I hand to RMA my MSI 290 Gaming and they're sending me back a retail box 390x because they're out of 290s. So I've been looking up benchmarks and the only single card that'd better than my crossfire setup when it runs is basically a 980ti. So I've been thinking and I have a few options:

 

1. Sell the new 390x and wait for something better.
2. Keep the 390x and sell my 290
3. Run them in crossfire as before
4. Sell both of them and get (insert card here)
5. Something else you can think of

What do you guys think I should do? The rest of my rig specs are in my signature and I game at 1080p. I'm also an fps and quality snob so I like to run everything at ultra over 60 fps. Personally just running 1 290 seems a bit laggy at times in the likes of Fallout 4 and it bothers me, which is why I was thinking of running the 390x as my main card which would be faster than the 290 then just have the 290 for crossfire when it runs.

 

Edit: added poll

Crossfire and hope the other 290 dies so you get a 390x

also                                                                                                                                                                                                                       (look below this)

sell 290

You cant crossfire 390x and 290.

[ALwin]

Send it to me.

If you were happy with your previous Crossfire setup just keep both cards I suppose, at least you will have the stronger card (390X) for the games that don't work well with SLI (e.g. CSGO, Fallout4, etc). Otherwise sell both and get a 980Ti/FuryX if you really want to upgrade.

[Razarza]

You cant crossfire 390x and 290.

You can Crossfire any AMD GPU as long as it is the same, so the 290, 290X, 390, 390X are all compatible with each other since they are all Hawaii GPUs. Another wacky example is the 7870XT, 7950 and 7970 will work with each other too since they are all Tahti GPUs. You will still be limited to whatever the lowest amount of VRAM (a 7870XT and a 7970 CF together will only have 2GB of usable VRAM).

Run them in crossfire:

Yep the only issue is that you might need to match the clocks on cards however I think they might be fairly close of each other and with cross fire it wouldn't matter that much (i.e. because of not getting 100% scaling it means that the performance difference between crossfire 290 and crossfire 390x isn't as pronounced as single 290 vs single 390x)

I'm pretty sure the clock speeds don't matter any more or at least not as much, when I had my 290s they were usually way different clocks speeds and everything was fine. I remember during summer I had to downclock one card to something like 900Mhz because of the heat. Games still ran fine even though there was a 200Mhz difference between the cards.

 

Edit - Unless both cards do sync their clockspeeds but Afterburner doesn't report it correctly, I dunno, I guess it doesn't really matter as long everything works.

I estimate I could probably get about $550 for both of them so that's that.

Yeah, I'd definitely downclock the 390

If you can get that then an extra $100 for a 980Ti seems pretty appealing.

Oh my god do people not understand crossfire. The 390x will crossfire with the 290, you do NOT have to run them at the same core or memory clock speed, you will run at the lowest available memory, so 4g.

My 290\390 crossfire just scored 16.5k with a 4690 dragging the score down in Firestrike at the stock clock speeds

Really? That's faster than dual 780ti's or a 980ti

And useless unless the game you play has a crossfire profile *sad face*

Yeahhh, that's the problem... However, assuming I could sell my 290 for about $200 and the 390x for about $350, that'd give me a $550 and you can buy a Windforce 980ti for $600...

Decisions decisions...

If I had the chance I'd sell mine and get a 980. Until then all we can do is hope Crimson comes out with more crossfire profiles.

Yeah, part of me just want's to sell the 290 and run the 390x (basically a 980 depending on the game + or -  a few fps) with the 0 fan mode and enjoy my computer in silence. It's really a shame multi-GPU support has gone down the tubes as of recent games.

The 390x is a beastly GPU. Unless you run higher resolutions you shouldn't need anything else. I want the profile to run Mechwarrior in 1440, the 390 can do it but I want the extra fps for multiplayer reasons.
