From my last post of my motherboard making a high pitch whining noise, it is slowly becoming more frequent and increasing in duration when it makes the whining noise (can only be described as sounding like its crying). Although it may carry on fine, I do not feel comfortable with it and don't want any down time if it decides to fail. However I am currently using an i5-2500k, Sandy Bridge and a MSI z68s-g43 motherboard. Although LGA1155 motherboards are still available (not as many), I can only find Z77 chipset motherboards, with what I thought was for Ivy Bridge CPU's. Could I get a Z77 motherboard to replace a Z68, if so which one? Or would it be more advisable to wait a bit longer and get a new CPU (haswell) and motherboard?
