Is there any real world difference between an E5200 and the other Core 2 Duo's?

Is there any real world difference between an E5200 and the other higher priced Core 2 Duos such as E7400 and E8400 if you overclock it to the same speed?

With the E5200 dropping in price to around $65, is there any reason to pay $50 - $100 more for a Wolfdale chip if you can OC it to 3.6ghz or more?

Larger cache and SSE4 on the E7000's and E800's help with video editing, but does it help in games at all? Is the multitasking power better?

With dual core are you able to tab out of games and open a web browser?chocobo7000

C2D 5xxx is more than enough for almost all of the games right now. You can also multitask with it like browse while playing. Think of having a better ram like 2-3Gb DDR3 or better. I can easily multitask while playing many games(except some system hogs like stalker, gtaiv or Cod:WoW etc)

Have a better Gfx card too all this will optimise your cpu to function to its best.(I reccomend you have good psu to ensure no power surge occours and damage your cpu components)

Forget buying another C2D for little increase in performance. try to OC it I've OCd it from 2.23GHz to 2.48GHz
