The PS2 was about 4-5 times the power of the dreamcast when all is said and done. The dreamcast as mentioned earlier in this topic WAS NOT TWO 64 BIT PROCESSORS, but was 1 128bit risc cpu made by Hitachi which was more powerful than the equivalent speed pc processor at the time. Its GPU was a power vr 2 which could render 9 million polygons per sec basic, but that fell to 3 million with special effects and shading and stuff. It had 8mb video ram and 24 meg of main ram.
The PS2 however had a custom 300 mhz cpu with 2 vector co processors (much like the cell now and its spe's), which greatly increased the power of the cpu when they were all used together. The GPU was custom built by sony and could do 75 million basic polygons per second, which came down to 20-25 million with effects on. YES the gamecube could only do 10 million with effects and this is apparent when looking at metal gear solid on the ps2 vs the twin snakes on the cube. The ps2 version has a much greater polygon count when compared side by side even though it is the older game, and lets not forget Gran turismo, can anybody really see that game being rendered by a gamecube? i rest my case. ( even the wii is bad now and that is supposed to be a gamecube x2.
The other real reason that some of the dreamcast games looked better than most ps2 games, was not because of polygons or raw processing power but because of the resolution of the textures (much higher due to more video ram), plus the fact that the DC could also use texture compression much better than the PS2 could (fit about 30 meg of textures into 8 meg of video memory), mainly due to it being an off the shelf pc video card.
Looking back at soul calibur, arguably one if not the best looking dreamcast game, the polygon count was quite low on the characters and backgrounds, although the resolution of the textures and all of the special effects made the game look awesome when all combined together.
So to sum up, the ps2 was much more powerful than the dreamcast, but because of it's difficult to program hardware and low video memory, it took a great developer to get the most from the system with games such as gran turismo 4 and metal gear solid 3, zone of the enders or moto gp etc etc:)
