RED 3GL and Graphics Card

I just installed RED 3GL and got the notice that my (64MB) graphics card didn't cut mustard.

Based on Boris' specs it should. It's a "supported" but not a recommended card. I realized that I can go into Preference's Render Tab and reset it but I am wondering if I should purchase another card like the nVidia GeForce4 Ti with 128MB or some other card that is compatible with the Powermac G4 1GB DP (Quicksilver 2002). I am using the GeForce4 MX with a dual display setup but I don't know if this is dimishing the card's ability to function in GL mode. Boris' test shows texture RAM at 57MB.

Boris FAQ suggests checking for a driver update to your card but I don't know if there ever was one for the nVidia GeForce4 MX ...at least I didn't find one on Apple's site.

TIA
