AMD’s RD790 will be known as AMD 790FX; this is something that we've told you before, but we still haven’t said that the RD780, the one with less PCIe slots, will be branded AMD 790X. This is the brand that AMD plans to use for this one.
Last but not least, there's the RX780 and, quite surprisingly, AMD plans to brand it as AMD 770, although AMD 780 would be much more appropriate.
Some of these boards are ready and are hitting the market as we speak and you can already buy Gigabyte's AMD 790FX.
