Good question. Here's what I do:



The middle row is Pentium 4s (PGA 478). I group them together.

The other two rows are AMD (Closest to us), and the farthest row is Intel Socket 423. They're both a large socket green fiber CPU, so they go together.

You could probably put them all together, but I separate out my 478s (I just throw them in a separate sandwich bag). I've never been charged sorting for that.

Does anybody else know if we should just lump them all together?
