Hello dkzhaos,
In regards to your inquire, recommending a motherboard and processor for you will be very difficult as it will depend on your specific needs.
I do recommend you to look over the internet for benchmarking information regarding Intel(R) processors and motherboard and with that you can get a processor model number that meets your needs and with that, you can go in to the following web site and get the list of compatible motherboards:
Intel® Processors and Boards Compatibility Tool - Home Page
If you need any further assistance, please let us know.
