I finally gonna upgrade my old ass box and I'm planning on getting me a nice TBird and o/cing it to Hell. However, I'm a bit confused about a couple of things. First off, are all Tbirds unlockable via the pen method or has AMD put a stop to that? I've been seeing these 266 Athlons pop up. Im assuming thats the speed of the FSB. Right? Do they offer a substantial performance increase over the traditional TBirds? Do i need 133 mhz RAM for them or are the FSB and RAM speeds asynchronous?
