Are T40s and T41s preferred over T42s?

Few days ago swapped my 1.5 Banias with 1.7 Dothan Works perfectly and took only one hour to do this.

Really? You can really just REPLACE a processor in T40 (Banias based) into Dothan just like that?
Any special requirements? Should I do anything else? it's only the CPU chip. correct?

By the way, have you felt any difference in performance? Moreover, how about the heat?

I could be wrong as my mind/memory is a little rusty on this but I don't think there are any real issues between Banias and Dothan P-m, I think the main changes were a bump in L2 cache from 1 to 2MB?

(It was a long time ago I last refreshed my mind on this stuff) The only issue I could foresee would be Banias->Sonoma, which was the revision before Yonah/Core Duo, and that I am sure wouldn't work.

However, I can't see why a Banias can't be replaced just like that for a Dothan.

Apart from games and 3D rendering, I think the main speed bottleneck these days with computers is the bod sat in front of it

That said, I do still use Word 5 on a PowerPC 133 religiously for all of my writing tasks...

Yes...just like that Difference in perfomance is hardly noticeable when surfing in internet, but when opening autocad then the dothan is little bit faster. But what i am very suprised about is the battery.....it lasts longer (remaining 51% and shows 2:00h.....full capacity 34)
