To find how much spellpower 1 crit equals, just divide dps/crit by dps/sp. The terms cancel out and you get sp/crit. You can calculate sp/hit in the same way.

So, if you wanted to make a spreadsheet of gear upgrades, you would want to list how much hit (listed on the item), spellpower (listed on the item), and crit (listed on the item + int/60), determine the dps increase from each of those 3 stats (using the respective derivative above), and add them together for the total damage provided by that piece of gear.

It's worth pointing out that this is just for maximizing your potential dps, with no regard to silly things like mana regen. There's no way to reliably model that, so I would suggest gearing for maximum dps and then swapping regen items if you're finding yourself perma-oom before the end of a fight.

So the initial testing was quite close, nice. This formula should match for the things that I had mentioned in almost every post about the discrepancies and Predicted DPS/Actual DPS not matching up. The above should give us a more precise number for gear values.
