Crossfire possible? 2 Different cards

Hi there,

I was wondering if it was possible to Crossfire a:
- Gigabyte Radeon R9 280X OC
- ASUS R9 290X-DC2OC-4GD5

I won the ASUS R9290X-DC2OC-4GD5, but if the crossfire isn't possible, is it worth it to trade it in for another Gigabyte Radeon R9 280X OC and crossfire these two? (which is possible so I've read).

Thanks in advance!

    No. Amd allows crossfire on architectures that are the same. 280x and 7970 can be crossfire due to both having Tahiti architecture. 290 should only be able to be paired with 290 or 290x with new Hawaii architecture.

    Excellent, thank you for the quick reply. Do you think it is worth it to switch it in for another 280X to crossfire?
  3. I think it would make more sense to sell 280x and try to eventually crossfire 290. The bigger memory bus and vram gives you far better future proofing than otherwise. Also, crossfire either 280x or 290 is kind of pointless if you don't have a screen with 120hz or a resolution of 1440p. At 1080p, 290 will max everything. If you don't have the high end screen, I would recommend selling the 280x and getting a great screen to take full advantage of 290.
  4. So if I'm correct, you're saying: Sell 280, keep the new 290, buy 1440p or 1080p screen?

    Correct. You want ALL of your parts to be relatively even including screen to avoid bottleneck.
