First - congrats on your return to roots 
I just acquired Quadra 800 - these were really nice machines - so much different than PCs from these times (unlike today, when most of inner parts you can find on PC motherboards...)

Perhaps 10/100 mbps card would be faster, but it would eat bandwidth of Nubus that could be better used by for instance ATTO Silicon Express IV.
I just acquired Quadra 800 - these were really nice machines - so much different than PCs from these times (unlike today, when most of inner parts you can find on PC motherboards...)Yeah, onboard video is really good in this generation of Quadras. In tests that I made using Norton Sysinfo it was about as fast as considered as one of the fastest Nubus video cards Supermac Thunder II GX(!!!) Perhaps Sysinfo is not the best in these tests, but still impressive results from built-in video. BTW - does someone know a better benchmarking program for video? So unless you want to go hires and 24 bit colour, it is probably better to stay with onboard video.
No, it won't be. See official info from Apple:
