Top speed is 466mhz, hard to find last I looked.

I upgraded to a 366mhz cpu in my 770ED.
A lot of little parts to remove to get to the CPU, time consuming.
If you can get the CPU cheaply, and don't mind the risk of complete failure
(breaking something), go ahead.
But don't expect a dramatic speed up.
If you really need substantial speed, buy a new machine. And if you are doing
3D CAD work, look for something with decent 3D acceleration (the 770ED has
none). I'd try and get something with an NVIDIA chip so you won't be left out
in the cold like those stuck with ATI chips in their ThinkPad, like a friend
with an beautiful A21P who had to give up and buy a Toshiba just to feed his
EverCrack addiction. (no DirectX 8.1 drivers from ATI (via IBM)).
I remember a friend showing me his CAD system running on a 450mhz PII with a
old cheap NVIDIA board. Fast and smooth, you could rotate the image in
realtime. Then he showed me the same thing running on a new 2Ghz Pentium IV
his floor manager has just bought, but with the built in Video on the
motherboard. It was herky jerky, couldn't keep up at all.
