Sam_missles :
I can actually get a 4590 used for cheaper than a 4460 used. Will the 4590 work for 2+ years?
Better than a 4460 would, assuming the 4590 is in good working order.
I'm still using an i5-3470 (few months shy of four years old) and do not think I am going to have any real reason to replace it within the next 2-3 years still.
