i'm currently using the latest nvidia ide driver (from the nforce 5.10 package) and everything works nicely. i've got an nforce2 chipset. from a few things i've read the nforce3's ide is possibly a bit more troublesome though that could be untrue.
when i installed the nvidia ide driver i did have some problems with the installed ASPI version (installed using ForceASPI). i fixed this by getting Nero's WNASPI32.DLL and copying it over the old one in c:\windows\system32 (backing up the old one first, of course!).
i'd say if you're not having any problems stick with the nvidia driver.
