Deus Ex Human Revolution Director's Cut worth it?

Wait for sale :D

Well, I've already play the games, I won't get it just for the sake of getting it, even with the 80% off...

Well, it is going to include Second-Screen (when Intel releases the app for the PC version), I think that's worth it if you got the original on a sale.

Also has the tweaked bosses, energy system, textures redone, and some other things.

idk honestly if you already have game + dlc (like me)

It's pretty much a good buy regardless. $5 for reworked boss fights, changed lighting, Missing Link integrated into the main game? Great stuff. Don't have the game but wanna play it? $20 is an amazing price for a game of this quality.

Have a Wii U? I'd get it on that. The system could use the support, and honestly it seems like it'd work very well. The gamepad is great when used well, and DXHR:DC does so from what I know.

I already finished the original and I've got all the DLC, so I won't get the Director's Cut. Not gonna replay the entire game just to see a couple of improved boss fights.
