could you check the performance on Facebook? This whole thing has me very worried about me order....
I don't have a Facebook account, but this is a very taxing webpage:

There are A LOT of images. Again, AdBlock disabled and Flash installed.
Screen resolution set to Best for Retina.
Screenshot shows a frame rate of 32 FPS, but they can dip into the teens or spike to around 40.
