Here is a really helpful and informative post that started on D2jsp and Reddit, and has built into something which should last the life time of the game. If you study this list enough, you will eventually know what a sell-able weapon is, and what a ZOMG LOOK BRO weapon is
Max DPS for each different weapon type!
The Reddit post can be found HERE.
What you start with are the base DPS numbers on battle.net. There is exactly 1 level 63 weapon for each weapon type, and they all have a special name. I have included the names of every weapon so that you can look out for them on the ground (the base name shows up when a rare hasn’t been identified). Anything ilvl62 and below can’t really compete because it has lower base damage AND lower affix damage (all crafted items are ilvl 62).
Affix numbers can be found here. Affix damage scales up per item level, currently maxing out at ilvl 63. Daggers and 1H Crossbows get gimped affix damage due to their weapon speed, but all the other weapons have exactly the same bonus elemental damage potential (that’s why faster weapons have lower base damage).
All types of bonus elemental damage except cold have exactly the same amount of bonus damage potential (including physical).
A base weapon can be modified by a second +damage modifier: Fine. This goes up to 40% base damage!
For the maximum DPS I picked a perfect damage range roll (from battle.net), a maximum roll on the elemental damage range, +40% base damage from the Fine modifier, a perfect +50% damage (this only applies to the base damage of the weapon), and a perfect +25% Increases Attack Speed roll (this is +25% overall DPS straight up, after all other factors).
The formula is thus: ((Base Damage) x 1.4 x 1.5 + (Affix Damage) x (Weapon Speed)) * 1.25
Format is weapon name first, then maximum normal affix DPS, and then maximum DPS with a cold damage affix. And without further ado, the current numbers (sorted by DPS!):

There isn’t much math to do with off hands, as far as I know. The best Mojos are ilvl 62 with a damage range of 110-405 and same with Orbs. There is a rare and legendary with the same damage range, so I’d assume you want to get the legendary.
After that it’s a simple calculation based on weapon speed (after IAS) for how much DPS the offhand will give you:.
Mace, Spear (1.5 post IAS): +386.3 DPS
Axe (1.625 post IAS): +418.4 DPS
Sword, Ceremonial Knife/Wand (1.75 post IAS): +450.6 DPS
Dagger (1.875 post IAS): +482.8 DPS
