Since it is a serial solution each PCI lane has an individual connection to to the bridge. It is designed so that multiple x1 lanes can be combined for greater bandwith. So right from the get go the potential is there for an x1 card that can handle 250MB in each direction (500MB combined) up to a x16 card that can handle a peak bandwith of 4GB (8GB combined). So even as PCI Express grows to accomodate faster data transfer it is going to be backwards compatible. There is also enough overhead that it is going to be awhile before it is an issue.The 3dfx SLI technology was pretty seamless. Each card handled every other scan line across the entire screen rather than the entire top or bottom half. They also included a bridge so that the two cards worked together. BTW 3dfx was eventually bought out by Nvidia. Want to guess where Nvidia's SLI technology came from? <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f609.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=";)" title="Wink    ;)"  data-smilie="2"data-shortname=";)" /></blockquote>
