There trying to scrap the AGP interface by only only offering half of there products as AGP (50% AGP 100% PCI-e). Just Like Intel has now scrapped S478. They've stop production or are going to in the next week. They scrapped the northwood a little while ago and now the s478 prescot is gone or going now aswell. you'll still see them on the shelves for the next 3months still bu no new ones are being made
