Hi, I'm in the process of building a new pc and need some advice on choosing a processor. I have a Abit-KT7A-RAID mobo and plan on overclocking. I'm stuck between the AMD Thunderbird, Athlon, and Duron. I have heard that the Thunderbird 750 is highly overclockable, up to 1100 mhz. Are the faster thunderbirds just as overclockible? I have also heard that the Duron 850 is good as well as the Athlons. Which one is the best performance wise and for overclocking?
