	The 68040 will run at faster clock speeds,
	plus it executes machine instructions in
	fewer clock cycles.

	Some of the real bottlenecks in the Amiga
	right now are the lack of

	1). bus access faster than 7 MHz
	2). 32-bit bus interface by custom chips
	3). support for 8 bitplanes on display devices
	4). support for higher display resolution
	    (1280 by 960 by 8 would be real nice 8^)

	When these get sorted out the need for a 68040
	(or two) will make more sense...
