You could apply Amdahl's law which says that a machine executing one
instruction per second needs one byte of memory and one byte/second I/O
bandwidth.  In 'real' machine terms, a 10 MIPS system should have about 10
Megabytes of memory and 10 MB/sec I/O bandwidth.  This is a rule of thumb. 
Modern processors and memory prices what they are, you will do better with a
bit more memory.  Now, what is the MIPS rating of a Flamingo?

The debate of MIPS/VUPS/Specs has already been beaten to death, thanks...

   "MIPS" is singular.  "MIPSes" is plural.
