Hey there, I recently came across an i7 4770 for a killer deal. It's been used, though, for 4 years. I am looking to upgrade my budget build which has a Pentium G3258 at its heart. How long do you think this particular i7 would last before problems or failure arise, assuming that it has seen (1) casual, everyday use or (2) hardcore gaming use over the past 4 years?
