Go Dynacorn. Most of the panels are made by the same company such as the 400 hood -only one company actually makes them. The difference seems to be how they handle them and what they are willing to accept. Otherwise if it is a part that AMD actually makes themself, go for that. I've been happy with all my Dynacorn stuff whereas I sent back a bunch of Goodmark because it was riddled with dents and was wavy.
