think of the endless possibilities... 1.higher than ever refresh rates 2.faster memory processing if built-in northbridge were also linked to RAM with an external data bus. 3.the AGP slot could be positioned anywhere on the board (limitations apply) since the built-in northbridge would eliminate the need to share a common transfer with the expansion buses. 4.Dual-Core Processor function would be optimized with two seperate northbridges (one in the card), the other still positioned next to the expansion slots. 5.the card should then accomodate speeds that rival that of the motherboard itself, since with the total data transfer speed of the card consists of the GPU and the northbridge. I am hoping to research more on the possibilities and to try to come out with something realistic.
