Hmmm... that's hard to say. I don't do much in the way of large-scale chopping, I mostly do resampling and basic editing of my own digital pics. From what I've read the GIMP is lacking many high-end features that would put it on the level of Photoshop. I would have to say overall around 7 or 8 depending on what you'd use it for (probably closer to 3 or 4 in a professional graphics studio), but there are more experience people than I who could comment on it.
