If anything ps3 was the point where they started designing with HD in mind. You want ps2 and lower. So for one example, the textures in Sonic Adventure (Dreamcast version) result in a pseudo-3D effect on a CRT, but become noticeably flattened on an HD display.

You could also give the famous Symphony of the Night a try, and see if the art really does match that example picture. Really anything ps1 era, and SNES as well.
