Memory bandwith in 32-bit color is extreme and thus slows the whole card down because it does not have the bandwith to handle it. That's why the GeForce DDR is good is only because of its DDR RAM

Sure it DOES bottleneck but it runs silky smooth at 800 x 600 at 32-bit color but, around 1024 x 768 that's a different story. It also can be the processors also, I have this relic dual 450 soon to have 700

Once I get it I will post some benchmarks. I am almost positive that at 1024 x 768 it is all fill rate and not the CPU. But I will find out soon

Spending $1200 for dual CPUs and Quake III is REALLY extreme if you ask me. But I am in love playing Quake at 1024 x 768 in 32-bit color
