Could you stop telling bullshit about SSE?! It is an additional processor command set. Basically it means that the CPU can do complicated calculations in a smaller amount of time. Is has nothing to do with 32/64-Bit it is more about the architecture (x86). And it will run on your PC if your CPU supports that command set.

aka....the processor takes small shortcuts when processing.

Yes and No. What it really means is that certain operations can be done by the ALU instead of doing it via code. Or in other words without a SSE-command you would have to tell the CPU what to do and with a SSE-command the CPU would know a command that does that. The advantage is that the operation would take less CPU-cycles thus less time.
