PCI Express as I'm sure most of you know, is the next stage in the evolution of computer graphics, replacing AGP. Before reading on, it may be worth your time checking out our
PCI Express and AGP comparison piece.
So far, PCI Express has been strictly an Intel affair, with the introduction of Socket T (LGA775). With it has come support for DDR-2, and the number of supported IDE channels has been reduced to only one, almost forcing a Serial ATA upgrade. This seems like an awful lot of components to replace for an upgrade so we could only recommend LGA775 if buying or building a new machine.
Considering PCI-Express, SATA, DDR2 and LGA775 are all middle ground products that reap very little benefit over their predecessors, they certainly aren't technologies to be jumping at both feet first. However, the latest generations of AGP cards are likely to be the last, with even the current generations being very PCI Express orienated.
