I have a G4 400 with an AGP Rage Pro 128. I'm sick of crappy graphics. I keep dreaming of a new machine, but in reality, if I had a better graphics card, my machine would do everything I need it to. So, I was thinking about what I might buy. A GF3 would be nice, but would it be too limited by my processor? Especially given I'm a student, if I can get similar performance out of a cheaper graphics card, I'd be very happy. Any ideas? And any ideas as to what kind of fps I'd get?
