The forseeable future appears to be PCIe. Most machines will have PCI slots for awhile, due to all the legacy PCI cards around. A PCI-X card that works in a PCI slot makes sense, (assuming it does in fact fit and work, I've never tried it) but it doesn't make the PCI slot go faster. > > > > > Single-head: output selectable between DVI, VGA and TV-out > OGD will have two dual-link-capable DVI connectors.

Whoever maintains the faq/features-list/spec should update them. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
