Dyson didn't even know where they got the chip. More then likely he knew very little about what was going on and was just preoccupied with developing a working prototype. Keep in mind that Dyson was only working on the hardware. Someone else was ultimately going to have the develop the software for SkyNet as well, so it's not like Dyson is the end all and be all, he is just "the man most directly responsible" to quote the Terminator.
And the heroes went to destroy the chip and lab because they thought it would prevent Judgment Day, not because the knew it would. Remember Cameron got rid of the future coda ending and Sarah even mentions that future is unknown at the end of T2. Cameron definitly left it open enough so that the nuclear war could still happen.
If you want my honest opinion over the series the story should have ended with the first movie. Everything is resolved in that film period. The rest is just details. T2 was a good movie, but the story itself is not really that interesting. That's why when I saw the same story in T3 with worse acting and less dynamic action, I was disappointed. No in my mind the original Terminator with the added scenes including the Cyberdyne Marquee finished the story.
