the boards are the same. period. you can certainly run a dual 800 from a QS 2001 in your '02 without any other modifications, and the benefit is not only two processors versus one, the single 800 on the QS 2002 (just like the single 733 on the QS 2001) has NO level 2 cache. none. there is a huge performance penalty from lack of L2 cache. that is why you cannot give away the processor cards from either a QS'01 733s or the QS'02 800s. virtually no one wants them. (i've got 5 of 'em if anyone is interested.) i have a QS'02 that originally had the 800 processor, and i replaced it with a dual 533 from a DA, and it works just fine. in bench tests with various utility apps and real work comparisons with real world apps, the dual 533 slightly outperforms the native single 933 that was available in the QS 2002. it is also a direct physical swap including the cooling fan and shroud, and no physical modifications are required. only drawback an minor hack is required to install 10.5.6. i have no clue what the other respondent to your question is thinking but ANY DP that physically fits the electronic connection will work. even the 450/500 DPs from a GE will work, except they won't have a power connector for the CPU fan. and all of the third part G4 DP upgrades work just fine, from AGP thru QS'02, no modifications necessary. the only DP CPUs that WON'T work are those from a MDD, because they physically won't fit, nor will the electronic connectors match up.
