ATi 4xxx with 8400GS for PhysX - anyone dabbled?

[phatboy]

I borrowed an 8400GS from work last night to have a go on my crossfire board

followed instructions online that mentioned extending desktops etc and then removing DVI from ATI to make the Nvidia think its alone and enable PhysX blah blah blah

Bottom line.....after 2 hours, couldnt get it to work

Anyone else tried and succeeded? and is it worth the hassle?

I am starting to think i might just wait to see if the ATi "edited" drivers ever appear.

Win 7

see i thought the only OS that got upset was Vista, as people have been testing Vantage with it on and off?

found a place that do the PCI PhysX cards for £30. tempted just to do that lol.

lossely related but;

If i wanted to play batman on my 8800gts 512, would i need a dedicated physx card to be able to run it with physx enabled? Because i notice the specs say you need a 9800gtx+ for recommended and i dont want to have to run down the gfx just to use physx.

pretty sure it should just let you use PhysX mate.
