New Motherboard? Please>quick reply!!

Hey guys,
I have a question I hope someone can answer, within the next 24 hours. I recently got an Intel Celeron 2.4GHz processor for Christmas, which I was definately chuffed about as you could imagine. The only problem is, that my motherboard could only handle a processor up to 1.6 GHz with a 370 Pin socket, the new one is for a 478 Pin socket. Here's the main question, would I be able to buy a motherboard that could fit that processor, my current Pentium 3 Ram, a PCI Graphics card, and an internal modem. And the next obvious question, how much do you think it would cost.
Cheers,
Greg
