I'm afraid it doesn't. That addition of NAND is made for maintaing the data needed for faster booting and similar (general) tasks (like the M$ Window$'s "superfetch"). Once you've started the system (any Mac OS) and launched the application (photo$hop, for example), the relevant components of the software "reside" in system memory, thus the speed of the process(es) greatly depends on the efficiency of the CPU/GPU plus RAM.
