If it doesn't have AGP, does it have PCI Express, the one which will replace AGP, though precious few and insanely expensive cards yet?
I can't believe they'd ever go so far BACKWARDS as to not have a practical graphics upgrade route - I remember the last generation of onboard / no AGP slot motherboards, and I'm amazed they'd do that again - mind you, this is Dull we're talking about.
PS. Checked and checked again - Nvidia FX5200, ATI Radeon 9200 (and slower SE) - and insanely expensive Nvidia Quadro FX, nothing else of any merit found on PCI ... were any ATI card bulders crazy enough to do one of their DX9 capable (9500 or better) models in PCI ?
PPS. If the motherboard has a space for AGP, and no connector there, that would be all too typical for a an OEM version motherboard, as is taking out tweaking options in the BIOS, having drives with OEM firmware that can't use the latest updates - sorry to rant, but the bigger an OEM is, the more likely they are to corrupt the upgradability of a PC.
