PCI? Graphics? Do you have a PCI graphics card, or PCI Express? If you have a PCI card its quite old, of you have a PCI Express, its quite new.
Im no expert on Pentium motherboards, but on paper this one looks ok:
Look for Prescott support, Dual Channel DDR 400, SATA RAID, ATA 133 RAID, 800mhz FSB, Intel I875P Chipset, Gigabit LAN. All those features will take advantage of that processor. One thing that wont take advantage of that processor is a PCI graphics card. Take another look at it and make sure its PCI, or PCI Express.
