I'm building an AMD system and wondereing which processor should I get a 1.2, 1.33 or 1.4-Is it worth paying the extra $70 or so to go from a 1.2 to 1.4? I'll probably do some overclocking and I know a 1.2 Thunderbird will go to 1.4. But I also know there's a chance I might not get a very overclockable 1.2 either. Got my MSI K7t Turbo limited board yesterday(w/o Raid)!!!! Please give some suggestions. Also someone tell me if this HSF is good enough for the Athlons:
