Nope, both will run pretty much anything you throw at them, IIRC and I could be wrong but it wasn't till the 6000 series that things changed for compatibility with nVidia dropping a few minor things. Stick to older drivers as drivers will affect compatibility far more than these two cards will.

As for DOS both cards have the same 2D engine so will both run DOS games the same, there is a chart out there that lists DOS compatibility with GPUs, might be worth hunting it down and looking there for what issues these cards have.

The only thing that comes to mind is that the first Splinter Cell game was written very closely to the GF3 hardware and may have issues on a GF4 (don't remember any details, please look into that by yourself if interested). Being from 2002 this isn't exactly an "older Win9x game" though... Can't think of anything else.

Nope, Splinter Cell works perfectly on GeForce 4 Ti cards. However, on GeForce FX cards, it does have some very minor cosmetic issues (shiny texture glitch) but that's only encountered in a couple of areas and doesn't affect the gameplay. Phil has a very informative video on that subject.

It's GeForce 6 and newer cards that break Splinter Cell's lighting and shadows.

In DOS, compatibility for GeForce3 and GeForce4 cards are nearly the same except whether the VBIOS includes the EGA 8x14 font or not. The only real problem that I can think of is that there are many variants with larger VIBIOS (up to 64 KB), giving you less space for UMB and/or the EMS page block.
