The Gamecube has a 405MHZ Copperwire CPU and the graphics chip can handle floating point operations of 13.0GFLOPS, no you didn't read wrong thats 13.0GFLOPS  over twice that of the psx2, what this means is that the Cube is a very powerfull poly-pushing machine (Oh-Yeh!). And the actual display capability: 6 million to 12 million polygons per second. Oh and did I forget to mention that the Gamecube comes with a modified DVD drive that takes DVD's that are a bit smaller than average (Hopefully this means we get decent storage cases for our games this time....). The Gamecube will come in a large range of colours and you will be able to plug in the new Gameboy advance into the controller ports. Also I am not sure if these last things are included or packaged but you will be able to get 56k modems and rewritable hardrive thingys - Cool! The Gamecube is also Networkable so you don't have to share your TV screen with your freinds. What I think would be REALLY cool, would be if there was a game (say Perfect Dark2) where you could have 4-players on each TV, Imagine having two teams of four, with each team being in a seperate room!!!!!!!!!!!

Some Graphical effects that the Gamecube can  push around the screen are:
-Full Screen Sub pixel Anti-alaising
-Alpha blending
-multi-texture mapping/bump/environment mapping
-24-bit Z-buffering
-Realtime texture decompression
-A whole lot more!
