The Core 2 Quad is from what I've heard, two Core 2 Duos stuck together.

Does this mean that:

1. The Core 2 Quad Q9300 is two Core 2 Duo E7200s stuck together?
2. The Core 2 Quad Q9400 is two Core 2 Duo E7300s stuck together?
3. The Core 2 Quad Q9550 is two Core 2 Duo E8300s stuck together?
4. The Core 2 Quad Q9650 is two Core 2 Duo E8400s stuck together?

Or am I just completely wrong?

Sort of, but generally the quad would be slightly faster since the dual cores are not harmonised as effectively (this would also depend on the OS & application). Also, the newer quad cores eat 95W, vs 2x65W for 2 dual cores. Not to mention the price...quad and associated mobo would be cheaper.

Edit: I misunderstood your question, core 2 dual = 1 die & core 2 quad = 2 dies each containing 2 cores. I'm sure there are slight differences but what it really boils down to is 2x Core 2 Duo E7200s =/= Core 2 Quad Q9300.

From what I've read way before, you're a bit correct. Essentially C2Q's are C2D dies fused together in a single chip package.
