    AMD offers greater flexibility with its multi-GPU solutions, letting you mix and match any two GPUs based on the same silicon. It was quite natural to expect a Radeon R9 280X to work in tandem with a Radeon HD 7970 GHz Edition from the previous generation, since the two are based on the same "Tahiti" GPU, which is now proven. HardwareCanucks managed to run that combo without a hitch, and log performance results across a bouquet of game tests. The publication also notes that one should be able to similarly pair a Radeon R9 270X with a Radeon HD 7870 GHz Edition (the one based on "Pitcairn," not "Tahiti LE"). Have a Radeon HD 7950? Feel free to add an R9 280X to the mix.

    Forgive me, but I thought the 280X didn't have a CF connector... Is the 7970 supporting CF over PCIe?

    No.

    Only ones that support PCIE CF is 290, 290X

    R7 260X is capable of both CF Bridge or PCIE. 7790 has the same features but are inactive.

    I presume the 280x was showing/running at 300/150MHz as it was the 2nd card and in desktop idle mode.

    It's really ironic that AMD have this big advantage over nvidia with mixing different cards, yet have this runt frame problem that completely neuters it.

    I hope they can finally properly fix the damned driver and release a WHQL version of it. It's about time.
