Mine is running with an 18F4620 @ 40Mhz.
Using bare bones code, just sending black and white picture data as fast as possible with the LCD directly connected (well as close as possible, about .2") to the PIC, I'm only able to get about 6 complete screen refreshes per second (switching back and forth from black to white).
Those LCDs aren't the fastest thing in the world...
