I created a wiki page so we can keep track of the results: http://www.bitcoin.org/wiki/doku.php?id=4-way_sse2
You might want to add columns for whether hyper-threading is enabled, number of physical cores and how many cores Bitcoin is using. Without 4way, I get very slightly better results when I have half of my virtual cores hashing. With 4way, I get significantly better performance when I have all my virtual cores enabled. I think I get about the same amount of hashes when hyper threading is turned off with or without 4way.
