Im planning on building a core 2 duo system and ive been wondering about the various version of the E630. There ar (atleast for me) 3 version to pick from ranging from 143 up to 209 EURO. Pentium® 4 Processor 630 FC-LGA4, "Prescott": 143 EURO Pentium® 4 Processor 630 Boxed, FC-LGA4, "Prescott": 159 EURO Pentium® 4 Processor 630 Boxed, FC-LGA4, BTX, "Prescott" : 209 EURO My question is: Please correct me if im wrong but arnt these all the same processor only the 1st one isnt boxed, what makes the differance between boxed and none boxed. There is no cooler included on the first one but other than that I don't gett it. With such big differances in price there has to be something im missing. This could be a dumb ass question but i never bought a proccesor before. Still gaming on a agp 9600 ffs. Ðivin1ty Don't mind the grammar english is not my main language.
