Apparently, the graphics and performance are actually better on the PC. With the console versions looking more "washed out" and texturized to improve performance. They also say there are more hitches in the console version. This is all according to the video review by IGN.

Also if you have a PS3 and XBOX, the one that looks better is supposed to be the PS3 as the XBOX graphics are dummed down more for performance. I do not know if the PS3 has performance problems as a result of this higher quality, however.
I'd say if you have a PC that can run Dragon Age, go with it for now. If you don't, then go with consoles. Like I said, I can't believe how fluidly it runs on the PC. Not one hitch, stall or jump with everything on high (The graphics settings are quite basic tho, with AA, graphic detail and texture settings only).
