mrjericho1991 :
but if he already does not had it,then i would go with gt 240 even gt 220 is good performer when it comes to physx
The GT 220 would do the job, but is a bit slower at Physx then either the GT 240 or 8800GTS, enough to not be the best buy for such a task, especially considering the Gt 220 will basically cost him the exact same and perform a bit worse. Yeah, as I said above, if he already has a 8800GTS, stick with that, if not, he could get the GT 240 and benefit from not having to use a extra pci-e cable for power. Cost wise, he will end up spending about the same on either a used GT 240 or 8800 GTS 320. The Gt 220 is def not a good idea at all considering its cost versus physx performance when compared against the other two, and should just be avoided unless you can somehow nab one in the USD 20 dollar range.
