<Please ask them for details. They may be speaking about CAD-type operations, which could be immensely assisted by SSE2's 4-way double precision vector floating-point capability.>

First, packed SSE2 IS 2-way double precision not 4-way.

Second, you forget that SSE/SSE2 have both scalar and packed versions of the same instructions. Scalar SSE/SSE2 can be used anywhere to replace x87 arithmetic. The advantage is to use a flat register file instead of the brain dead x87 stack.
