I want to create an arcade cabinet for my church, and fill allow an user to select from 1 of 3 games. I wanted to used a Raspberry PI, but it seems like the highest 3D graphics a Raspberry PI can render is PSP, and I'm looking for something PlayStation 3 level, (maybe a tad bit less.) I'm looking to be able to render a simple game like chess, except have the chess pieces be 3D modeled. The reason I'm looking for something higher then PSP is because I want to rival iPhone and android graphics enough so the kids and adults would want to play the arcade cabinet. which microcontroller is powerful enough? what types of specs am I looking for? thank you in advanced.
