as for the e6800.. ehh... its not worth it unless you got money coming out your ***... ocing to 2.89 ghz is easy as taking a ****...... you really won't even notice the difference because they're all so **** fast... so why not save money?
Halla lot of swearing going on, try keeping it clean maybe?
I don't own an intel (yet), but if you have 2500 to blow then get the 6800 otherwise buy the 6600 and send me the 600$
