The 5870 is supposedly almost identical to the Current 4870. GDDR5 is just the graphics cards' base memory. Most of the time, the only thing the involves your motherboard that has to do with graphics card is your PCI port. It has to be a PCI Express x16 for a 5870.
And it probably means it will support DX11, which is currently in development. DX11 is based on DX10, so anything that needs DX10 will most certainly work with DX11, or at least that's how it goes.
Who said I couldn't have everything?
