BTX, SATA, 64bit. Oh my.

I don't know if the AGP idea will become fully obsolete, atleast there's room for revision, and offering multiplied speeds, as AGP has always been designed for. Sadly though the current AGP will become basically obsolete, only partially will it be supported by ATI. But perhaps we'll see a video card port based on HyperTransport technology. And PCI-Express isn't as flexible as InfiniBand, and doesn't have the bandwidth that HyperTransport does, which means PCI-Express isn't as well suited for communication with the RAM.

Hypertransport on a 64 bit system allows 12800 MB/s, compared to PCI-Express, which would be 500 MB/s, taken times the multiplier(16x for example would be 8000 MB/s).

For example, want to know why nVidia boards are fast? There are some that utilize HyperTransport, and they can be implemented transparently to the standard system.
