If you have heard bad things about this edition performance wise, it's in the past. Played it around 1 or 2 months ago and had no issues whatsoever.
Game itself is quite good. Liked Fallout better, but had fun with this one as well. Combat might get a bit dull after a while, but everything else was alright. Main story was solid, but don't expect anything groundbreaking, same goes for side missions and DLCs. World / atmosphere was really cool, companions and dialog options were a lot of fun. You can take the usual evil/good path and slightly change the world (available missions) around you.
