According to this report at DigiTimes, ATI claims that PCI-Express will grow to take 50% of desktop motherboards in the middle of the year and 90% around the end of the year. I'm a bit sceptical about this. PCI-Express gives you almost no advantage over AGP, except for dual-card solutions like NVIDIA's SLI. On the other hand, if manufacturers for office computers jump on the PCI-E bandwagon we might see some huge PCI-E growths. Also in this article ATI says that caused by Intel's new Sonoma notebook chipset, they expect PCI-Express support to rise to 60-70% in the notebook segment during this year.
