It depends on how you value things. If you want to value something you already have, the value is either what you could sell it for, or the cost of replacing or improving it.
If you want to see the options for upgrading that old G3, look into the lowendmac site.
If you want to replace it, the value of your machine becomes pegged to the cost of a new machine (which also depends on what you want to get) less the improved performance. Cost of the new machine would also include the cost of new software.
If you have a machine that works, why replace it?
