So when they talk about the socket, like 1155, or AM3+ do same "names" fit under each?
if the i7's were 2011, would core 2 quads fit the 2011?
If the Phenom 2's were AM3, would any athlon fit the same socket?
After a while you start to remember what goes with what, but you don't have to memorize this stuff. When looking at a CPU you are interested in, the socket it goes in is usually listed with the other specs.
