A 25Mhz 68030 Amiga (the A2500/30) is somewhat slower than THE 25Mhz 68030 
NeXT, though if I recall the benchmark posted (Dhrystone 2.1), you couldn't
tell that from the difference in benchmarks, they were close enough to be
the same with a change or two of compiler options.  The A2500/30 doesn't
support burst mode, where the NeXT does, and it also has a slower hard disk
interface (fast enough for asynchronous SCSI, but not quite for synchronous 
SCSI, and at that eating most of the bandwidth).  There are other A2000 plug
in boards, like the one from GVP, that are faster at 25MHz than that NeXT
machine, if you want to spend a little more than the cost of an A2500/30.  But
the A2500/30 is an old machine; the A3000 is as fast as the original NeXT in
CPU/memory and at least as fast in hard disk.  You'll probably find the same
results with 68040 boards for the A3000; some may be slower than the NeXT
machines, some may be faster.  Who cares?  When someone make a 68040 board
for the A3000 that makes it as fast or faster than a 68040 system from HP,
then we'll have something to brag about.
