My motherboard, an Intel Peter Cove, after only 3 years went dead. It came together with an i3-540 3.06 GHZ 4MB. I am thinking to buy an Gigabyte Z77X-UD5H motherboard and still use the old processor for a year or so. I am not sure if the new Gigabite will accept the i3. Are there any arguments against this idea or should I make efforts to get a new i5 or i7?
