I have owned either a GTX260 or 280 since Nvidia started with this physix crap and have never played a game that uses physix and don't have an urge to pick up any game that uses it. Mirrors edge sounds like a bore fest and Cryostasis dosen't sound much better. All Physix did was bug up Nvidias drivers for MONTHS. Physix is a joke that will NEVER take off. I'll pick up one of those stupid Killer NIC cards before I buy a dedicated Physix card. Ambient Occlusion is a bigger deal to me than Physix and I have only used that once but it was pretty cool.
