I am brand-spanking new to the overclocking scene and I need some help. I bought an IBM Aptiva (model 2163-580) with a pIII 450. I hear some off the shelf comps are close to impossible to overclock. Is this the case with my computer? If you want to check out all my system specs, follow the big *** link at the bottom. One more note, I have a Voodo5 5500 AGP.
