BTX will replace the 7 or so year old ATX form Factor, and with that change comes a new Graphics standard. x16 PCI Express will replace the current standard AGP. The following paragraph is from www.anandtech.com about the new motherboard layout, and standards. These changes are set to take place during 2004 "Graphics in BTX The vast majority of BTX form factors will see PCI Express based graphics as the choice of video card in these systems. ATI has already announced that they will be releasing a native PCI Express video card once the standard becomes available in platforms. Although you can have multiple widths of PCI Express buses, graphics will use a x16 PCI Express implementation that offers 8GB/s of bandwidth." This increase in bandwidth from 2.1GB/s to 8GB/s, will no doubt aid graphic intensive tasks like games and image rendering. Will Apple follow suit or stick with the AGP bus? One thing that stands out above all else though is that the layout closely resembles that of the single processor G5 boards, especially with the heat sink design. And the strong focus on quiet coolong A final word It will take quite a while before the death of ATX; and although we've done a lot to get rid of the "beige box" the final nail in the coffin of boring computers will be driven by BTX.
