There are still good motherboard for lga775 cpu's that use DDR and AGP, for example I am getting the Abit AS8. It uses the 865 chipset, has SATA raid, which I need, 8x AGP, so I don't have to replace my video card, and uses DDR, so I can keep my current memory, so there are still options out there, that wont' force you to replace everything.
