Also,

most motherboards today support VT-x. However it is better to check with the motherboard vendor to make sure their BIOS enables VT-x capability.

On the processor side, most of Intel's desktop, WS, and Server products support VT-x today. Depending on the processor the customer wants to buy he can visit the specific product web page on Intel.com to find the details.

Here are some handy links on core 2s
