Crossfire with 7970 and R9 280x?

[nutsnut]

Hi, currently have a Gigabyte 7970 windforce and was looking to go crossfire with another, but they appear to have all vanished from stock at reasonable prices and it is now cheaper to pick up the Gigabyte R9 280x.

I understand these are rebranded cards so will they still run in crossfire?

Looking around online it seems like it should work, time to take a gamble,

Iv read it works

Just trying to find a pm R9 280x that doesn't have a boost speed, want clocks to be the same on both cards at all times.

I have the same problem. Have a VTX 7970 x-edition which only a few days ago was out of stock and pulled by OcUk. Wondering to wait and see if I can get aniother or go for a 280x...

You should be able to disable boost with a custom BIOS. Dunno if they are out yet though.

It seems all the R9 280X's feature a boost bios

May need so source a 7970 from elsewhere, though i prefer to buy from OCUK.

Any more 7970s coming in Ocuk?
