Crytek claims they used this system to tweak the performance of Crysis Warhead:
Interestingly, Crytek producer Bernd Diemer told Remo there's more than mere marketing behind the Warhead PC. As the story goes, Crytek built the original system in its Budapest, Hungary office and used it as a reference during Crysis Warhead's development. "If frames were dropping on the Warhead PC on a high graphics level, the team would tweak the game to better scale to the hardware," Remo explains. Crytek went so far as to run "all milestone presentations [it] did for EA" on the PC. Because of those efforts, the Warhead PC can supposedly run Crysis Warhead "in high spec at an average framerate of 30."
