You mean Prince Of Persia 5
The need for hardware is usually overrated. I fully expect to play any game that's released in the next months to be reasonably playable on my P4 2 GHz with 1 GB of RAM and ATI 9800 Pro. Bought the PC in a supermarket and just upgraded the RAM and graphics (+ HD). Far Cry, Doom 3, Half-Life 2 made no problems, why should Psychonauts? I think I played them in 1024x768.
Just checked: yes, true for Far Cry and H-L 2, Doom 3 wants the CD.
