You can get some of this from Google Scholar's metrics pages, which list, for each venue, the most-cited papers since 2008. These indeed seem to be different than the best-paper selections, though I haven't examined this systematically. (I guess you could take the best-paper and look at its citation rank out of papers that year. But this raises other questions; for example, is the point of best paper award to select the paper that will be most influential?)

From this page, http://scholar.google.com/citations?view_op=top_venues&hl=en... , click "Subcategories" under "Engineering & Computer Science": for example, "Artificial Intelligence," "Computational Linguistics," or "Human Computer Interaction." It lists the most-cited-venues for each area, but if you click on a particular venue you get its list of most-cited-papers.

Here are a few that are also on Jeff Huang's list:
