Not sure of bounds yet, no one is high enough. That pretty much goes for all stats too.
My saves are as follows:
Cold Resist 44
Heat Resist 102
Poison Resist 21
Disease Resist 159
Magic Resist 38
Divine Resist 32
Mental Resist 102
I am currently level 21. I would think they would have some sort of soft cap per level, whereas your numbers can be higher but it only actually has any benefit up to a certain number. Then again, that could be wrong.
Truth is, until someone starts finding crazy resist gear and we get people tossing out major resist buffs we won't know what we cap at.
