The one thing that no one has mentioned (or known about) is that one drawback of the MMX is that the MMX function of the CPU cannot be used at the same time of the floating point unit. So any of your games or other programes that use the MMX and uses the floating point unit will be slowed down, because the two are constantly switching back and forth between one another. Although the Pentium Pro can get around this problem because it's so fast at switching back and forth that there isn't a slow down. Just a little unknown piece of information about the chip that is being kept silent by Intel. So I wouldn't spend the money.
