I’ve had sites with high PR that don’t get much traffic, while others with low PR get a lot. PR is only a small fraction of how you rank.
If you have a high PR but only a few pages you won’t do to good. Unique content and lot’s of it helps bring out the benefit from a high pagerank. How many backlinks and how relevant your content is to the search query and the age of your site, is even more important than Pagerank.
