Okay so I have a dell xps 420, don't really want to replace much besides my gfx card, bump up from 4gbs to 8gbs of ram and obviously up my psu wattage to handle to upgrades. I don't want to replace my quad core q6600 cpu yet but I do want to overclock to about 3.0ghz. Obviously you can't overclock the cpu, or any part for that matter, in dells without physically altering the chip because of the bios limitations. My question is, when I transfer these parts into a new case with a new mobo, will I then be able to overclock the cpu?
