A solution that works for me card BCM4322.

Impact Factor of Computer Science Journals 2012

The Thomson Reuters Web of Knowledge has published the 2012 Journal Citation Reports. Following similar studies I performed in the past six years (2007'08'09'10'11'12) here is my analysis of the current status and trends for the impact factor of computer science journals.
Let me start with an overview of the method I followed. I performed my analysis on the 467 journals appearing under the Web of Knowledge's computer science subject categories: artificial intelligence; cybernetics; hardware & architecture; information systems; interdisciplinary applications; software engineering; theory & methods. Note that journals may appear in many categories. In particular, there are many overlaps between the above categories and "electrical and electronic engineering" and "operations research and management science".
Don't take this report too seriously. The impact factor is notoriously prone to misuse; let's not make the situation worse. Also note that in computer science there are tens of prestigious conferences. For a ranking of these conferences you may wish to consult theConference Ranking Exercise performed by the Australian Government's, Excellence in Research for Australia body.
