Anyone ever heard of a main board that has dual cpu
one X86 and one PPC. Would it even be possible.
Possible: sure.
Done: Probably not.
You can get PPC based PCI cards though but you'll probably pay $$$ for them.
With the 970 and Opteron wouldn't it be possible to make such a board? Both use Hypertransport...
Only Opteron has HT at the moment - but IBM have just joined the HT forum :-)
