The price difference between both LGA775 specs LGA1156 specs (core i3) i mentioned is not too much, but that extra amount of money guarantees you atleast 3 years of usage & safe investment. No to mention that Core i3 having a smaller die size (i.e. 32nm) has lesser temps & is more overclockable and performance is equal to a Dual Core from LGA775 (e8400) which costs 14k.
