Physx

[Tommyd]

I have heard of hacked drivers which allow you to run Physx with ATI primary card.
Assuming that is correct, I have a few questions.
1)Which games actually use Physx?
2)Which would be better, a GT 240 or a 9800GT for Physx?
3)Will either of those cards work in a PCIe 2.0 x16 slot in x4 mode (4 electronic connectors, 16 physical)
4)Is there any gain to be had from a Physx card?
5)My motherboard has an integrated HD4200, which isn't used, will this affect anything?

This should help explain things. There is also a list of games. PhysX - Wikipedia, the free encyclopedia

Yeah, that did help, thank you. Although it hasn't answered questions 2, 3, 4 and 5

2) The GT 240 is a better card.
3) They both will
5) No, this will not affect anything.

Also, i wouldnt say you need to have PhysX.

EDIT: Ive never been without it, so wouldnt know what happens then?
