Just like it sounds. I'm building a new computer but i need to know how long this will last. My friend mentioned that, where he works, their systems that runs servers with xeons have to replace them at least twice a year.
What are you going to be using it for? If the CPU is going to be under 100% load 24x7 365 I can see other components going out under that high pressure situation but normal use I don't think you will need to replace anything twice a year.
