I'm lookin for a new processor, I'm having probs overclocking the 2000+ that I have right now.... I heard that chips w/ the palamino core are tough to overclock... anyway I want to buy a 2700 + but I want to make sure that it is a Barton because apparently those are easier to tweak. Also is there a difference between an OEM chip and a retail? cause from reading some of the other posts some people perfer OEM My sys rig at the bottom is the pc I want to upgrade. I'm planning to place the order tonight so any help would be appreciated. Thanks
