With the Intel chips the most important difference is that the PC6400 (which is 800MHZ) gives you more headroom when OCing. It will also give you a small boost but not really a significant one.

Note that another factor to consider is the timing (again, less important with the Intel chips) because PC5300 CL3 will give almost the same performence as a PC6400 CL5.

take a look here

PC4200 (533mhz) allows stock operation and no overclocking, PC5300 allows mild overclocking (1333mhz or 333mhz FSB) and PC6400 (800mhz) allows as stated more overclocking head room (FSB1600 tops)

me? im using PC6400 to allow my E6600 to get to FSB1600 speeds
