dell sucks! they have an 'dell' chip implanted on their mobo's where the fsb and so on is described! i don't know exactly what is in the chip, only that the chip is the reason that you can't overclock any dell, so i guess that the originally cpu is described in the chip and more! advice: buy an new mobo AND PSU, the separate parts of the dell can you use for a new to build computer. also the psu, its, again, a dell psu wich you can not use in another computer!
