I am upgrading my wife's computer this month. Before I purchase the parts I would like some advice about dedicated PhysX.

Here are her specs to start:

AMD FX 4100
AsRock 970 Extreme4
8 GB Crucial Ballistics DDR3 1333
2 GeForce GTX 460 in SLI
Antech Kuhler 620 Liquid-cooler
PC Power and Cooling Silencer MK2 950w PSU
Corsair White Graphite 600T Case
Seagate Hard drive 7200 rpm

I am upgrading it to this if all works out:

AMD FX 8350
AsRock 970 Extreme4
16 GB Corsair Dominator DDR3 1333
Gigabyte Geforce GTX 670 2gb
EVGA GeForce GT 640 2Gb (Dedicated Physics)
Antech Kuhler 620 liquid-cooler
PC Power and Cooling Silencer MK2 950w PSU
Corsair White Graphite 600T Case
Corsair Force Series GT 120Gb SSD
Seagate Hard drive 7200 rpm

Will the Dedicated PhysX card cause any slow downs since its a GT model? I can get this card for $80 where buying a GTX2** used off eBay will cost the same or more and has half the Cuda Cores to process PhysX. And forget about any other GTX series newer than the 2** series. The 2 460s I am removing from her current setup are spoken for in two other computers I am setting up. And the GT 640 has more Cuda cores anyway, but if it is recommended to be better I can use the GT 640 in a diff. machine and a 460 in hers for the PhysX.

Any suggestions are welcome. I am trying not to spend a fortune on the PhysX Card. She plays Several PhysX games though such as Alice:Madness Returns, Batman A/C, Borderlands/Borderlands 2, Mirrors Edge and a few others. So the dedicated PhysX should speed up her primary card and allow for better graphics quality and higher FPS without sacrificing the PhysX effects. Am I right?

Also which slot would be best to install the card to? Does PhysX need a high speed slot like an 8x or will it work just as well in a 4x slot? I assume that if I install the 670 in PCIE2@x16 that I can install the 640 in either PCIE4@x8 or PCIE5@x4. Not sure I am understanding that right but here is what the manual says for the slots on the mobo. Let me know if I am right or wrong:

*3 x PCI Express 2.0 x16 slots (PCIE2/PCIE4: single at x16 (PCIE2) / x8 (PCIE4), or dual at x8 (PCIE2) / x8 (PCIE4) ; PCIE5: x4 mode)

Here's a link to AsRock for details on the Mobo:http://www.asrock.com/mb/overview.asp?Model=970%20Extre...

Thanks for your help!
