4.6 Ghz quad core? Aw yeah. http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3184&p=1
The article had a ton of great info about overclocking and the pros and cons of doing it, several of which ahve been discussed on the list. There is also a really thorough analysis of the power consumption. While these chips are still out of my price range, I can't wait to see what the lower-end 45nm quad and dual cores can do. -- Brian Weeden
