Am I really confused? Tbird DDR or not, a real difference?

I seem to have read somewhere that the new T-bird DDR would be the same thing as a regular T-Bird unlocked... If I want to change my CPU, should I save the 30$ difference between the regular 1 gig T-bird and the DDR T-bird and buy myself a #2 lead pencil for 25 cents???

If not, is the new DDR T-Bird worth it? I can't seem to find any serious article comparing the two of them...

DDR memory modules don't have anything to do with the CPU, really. It's the motherboard and chipset that matter, specifically the Northbridge-chip (I think,still learning this stuff myself;)). The Front Side Bus, or FSB, that runs between the N-bridge and CPU, is what your CPU cares about. Athlons/Durons have always used a 100mhz-DDR FSB, but new chipsets are bumping that up to 133-DDR. If your CPU is designed for a 100-DDR FSB, then the 133 FSB will result in a %33 overclock if you're REALLY lucky, or the need to unlock the CPU and fiddle around until with the multiplier.
The N-bridge on the AMD-750 and Via KX/KT133 only communicate with the RAM once per clock cycle-in other words, the memory is SDR=Single Data Rate. Newer chipsets are using a DDR interface between the N-bridge and RAM.

Like i said, I'm still learning this stuff; did I come close to getting it right guys?:confused:
