oh wow ok i didnt realise that ! i was half considering ugrading when 1155 was a thing and i know sandy was the main one then ivy was the refinement then haswell and broadwell etc
not looked into it much since then !
the key is in their names
you had the (sandy & ivy) bridges, then the (has & broad) wells, then the (sky, kaby, coffee, cannon, ice, comet, rocket) lakes and it's been lakes ever since for like 6-7 years of lakes upon lakes and every year they just rehashed the same thing over and over and over and over...
