I played DAO&DA2, multiple times, on PS3. I re-bought them for PC.
DA:O constantly ctd. My drivers are updated, I tried the "setting the affinity" thing, but it never goes more than 5-10min without crashing. In or out of battle. The only way I got out of the circle tower OR the deep roads was killallhostile spamming. I can't get into the game that way.

DA2, however, plays smoothly for hours on PC and I liked using hotkeys! I liked it a bit more than PS3, but I still prefer the console. I really like controllers. Makes me feel closer to the game!
The only thing I like about PC is being able to use mods. I am so glad I'll be able to use the controller but still get the full experience of the game because I got this damn gaming laptop and I'm not forking up any money for a ps4 anytime soon.
