What mother board and CPU?

I would like to able to have atleast Duo cores but quad core would be nice, and I would like each one to be atleast 2.4GHZ and it needs to be PCI 2 not PCI 16, so I can use the RADEON HD cards.

Thanks Sam

My budget is £200 for motherboard and CPU and No to the crossfire
