[quote name='shrike4242']Computers with the 810e chipset (Pentium III-type) and 845G (Penitum4-type), as well as 865G (Penitum4-style) came without AGP slots, because they came with built-in graphics for low-end PC's.[/quote]
Nit-picking here, but the 845G and 865G do have external AGP graphics support in them (and in the same vein the 915G has external PCI-express graphics support). To be more precise you actually mean the 845GL, 845GV, 865GV, 910GL, 915GL, 915GV don't support any external AGP/PCIe graphics.
