"Ageia and their PhysX technology have taken some serious flack since they first introduced the idea of a dedicated PPU (Physics Processing Unit). Despite this however, they have struggled on, getting their hardware supported in many a popular game. Recently, Cell Factor also came into play, a game that practically runs like a PhysX benchmark. Just over a year on from our original PhysX review how have things changed and is there any difference between the two currently offered choices for a physics junkie; the BFG and the Asus? We hope to answer these questions in this review."
