Yeah the main cpu will be taxed about 5-10% during heavy load, where as a good onboard controller will have it's own processing unit and additional cache.
You won't see a huge increase in performance really though, not for single user stuff, as most software is optimised to minimise disk writes during operation anyway, of course if you have background programs running that write to disk this will be more transparrent.
Until the first pci-e cards come along there is little gain to be had from having more than 2 drives striped other than the fact that 60-70mb/s is usually their peak read rate and their slowest is uaually around 40mb/s, so more than 2 striped would give a consant peak rate
