Cheapest Core 2 Duo Upgrade Route?

[PermaChanged]

Hey guys,

Whats the cheapest way to get a core 2 duo setup? I understand just get the cheapest C2D the E2140 and I'm happy to and I know how to overclock.

But what motherboard and memory would be the best for overclocking it to say 3ghz on a tight budget?

Thanks

Do you know if you can run a Sata 2 RAID 0 with the onboard chipset or doesn't it have a raid controller?

I could even use the Asrock board as a stepping stone to allow me to keep my current ram then upgrade again when I can get RAM and new Mobo. Decisions decisions!
