Mario Galaxy certainly looks better than Doom 3 would look if you played it on a GeForce 3.
@Viper, the PS2 was a 64-bit CPU. It was able to perform SIMD operations on vector data stored in 128-bit registers (usually 4 32-bit floating point values), but so is the Pentium 4, and we don't call it a 128-bit CPU, we call it 32-bit. In fact, we have had 64-bit and 80-bit FPUs for decades now, but the "bitness" of a CPU is typically defined by the size of its general purpose registers and memory address space.
The Gamecube and Xbox both had 32-bit CPUs and 64-bit data buses. The Nintendo 64 had a 64-bit CPU and a 32-bit data bus.
Bitness is a pretty poor way to judge a CPU's performance. Generally, 99% of integer code is 32-bit; 64-bit general purpose registers don't become important until you need a virtual address space larger than 4 GB.
