Performa vs. Quadra
fusiong mail
for my kids. What's the basic difference between the two?
Also, obviously there's a big difference between 25 MHz and
66 MHz machines, but for running games and kid's educational
software, are the extra dollars for the speed worth it?
Finally, if I buy a used low end Performa/Quadra, is it easy
and/or reasonably low cost to upgrade the CPU to a faster one?

For the most part, Quadras have FPUs (the chip that speeds up math
functions drastically), while Performas don't. Otherwise, there is
usually no difference. The exceptions I remember off the top of my head
are: the Powermac Performas have FPUs, and Quadra 605s do not have FPUs.
Note that FPU upgrades for 68040 machines costs $250 on up.
FPUs are almost never used in games and educational software.

Well, guess what are the most powerhungry apps? Games tend to require a
faster machine than currently exists to be really good. (another Murphy's
law...)

In every instance that I have ever seen, it is cheaper to sell the old cpu
and buy a new one. The upgrades are often rather twitchy, to boot, and
you usually lack pieces of new technology.

The Quadra 630 (and its other-market counterparts) lack FPU's as well.

Wrong! The Quadra 630 has an FPU. I know because I own one and
snooper detects an FPU is installed. It also says it in the manual.

Performa and LC 630s have no FPUs (that is, they have the 68LC040).
