Oh yes for this part, I have seen some interesting board. I have seen too a Gigabyte and Asus board with both AGP and PCI-Express.
Don't go there...
Get a PCI-E motherboard (no AGP), either an AMD AM2 (cheap) or an Intel Conroe (starts at $180 for CPU).
If you keep your current card you will be stuck with an AGP board that will have a crippled PCI-E slot (if any). You will be investing in throw-away parts.
