PC2100 with a XP 3000+

[laserdemon]

My p4 system reciently fried and i was wondering what kind of performance hit am i going to take by using my old 512 stick of pc2100 with a new xp 3000+. I will be using the new MSI KT880 motherboard that I just won from ViaArena.com. If i need to buy something new as far as memory goes i will. This board is dual channel ddr so i guess id buy 2 256 sticks. TIA

nm, i went ahead and bought a 3200+ and a pair of OCZ PC3200 chips.
