My question is the title... Is a GTS450 good for dedicated Physx card? Going to be using it in my signature system. Currently using a GTX285 but the noise it makes is pissing me off as the rest of my system is virtually silent. Or would it be better to go for a 768meg cheap GTX460? This question is aimed at people who HAVE experience using a powerful dedicated Physx card for multi monitor gaming/3D gaming. Please no "Its too powerful just get a GT240" comments. Thanks!
