i don't know what Dell is doing these days, but i know that their dimension XPS systems used to have mobos made by intel. of course i had my dell almost 5 years ago. but assuming the mainboards they use are still ones made by intel, know this: boards made by intel are not OCable. they are the most reliable and stable boards available, topping Abit, ASUS, and all other reputable mobo makers. but intel mobos are made for this, and only this. if you're an enthusiast, you can do nothing with a dell.
