Hello, I will be making a very very very cheap system and wanted to put the cheapest 775 socket CPU. I found this, Intel Celeron 420 Conroe, and was wondering, what is the overclocking potential of this cpu? could i bring it up to around a 2.9-3.0 to use until i have the money to upgrade to a e6550 or e6750? I will be using the computer as more or less a project rig, but i will have a TV tuner and big screen to also use as a TV/dvd player
