Well, this isn't quite true. The CPU doesn't care, but the motherboard might.

Intel would *prefer* that you left the damn thing alone. They have tried their
hardest to muddy the waters by having three different pinouts between DX, SX,
and OverDrive. This makes it difficult to just swap in a new chip for an old.
The idea being that if you can't swap then you'll leave the old one alone and
not glut the market with these pulled chips.

If you remove the SX chip then you will leave some motherboard inputs
floating. This has the potential of introducing major flakiness into the
system. Maybe the motherboard designer anticipated this and added resistors
to the motherboard inputs, and maybe he didn't. Considering how cutthroat the
business is these days he probably opted to save a few pennies.

In particular the HLDA output from the SX is quite important. Depending on the
specific motherboard there could be others. Of course, you can replace the SX
with a cheap header that has some resistors on it.
