Hello there. I'm trying to get an Nvidia GPU just for using it as a second card, more exactly to do the physx on Mirror's Edge. I found a 8400GS for 34 Euros, would it be enough for this? I don't know if I need a more powerful one, because it would be only used for that purpouse. Oh, another thing, would my PSU be enough to handle both my ATI and Nvidia cards? Any suggestions? Here's the link to the GPU http://www.appinformatica.com/tarjetas-graficas-point-of-view-geforce-8400gs-256mb-pcx.php
Unfortunately those cards are next to useless for a dedicated PhysX processor. To get the full benefit from a dedicated card, you'll need at least a 9600GT
Ok, so here I found a 9500 and 9600, but the difference between price its pretty impressive Is my PSU enoguh?
I see that your primary card is ATI. Unless something has changed that I'm not aware of. I don't think PhysX will work even if you have a secondary nvidia card to do it with.
Why in the world would anyone buy a separate card just to run PhysX? This is the same concept as buying the dedicated PPU cards which flopped so hard even before NVIDIA purchased PhysX. Most people that do run a second GPU for just PhysX already owned the card and bought a better card for the primary, they didn't go out and buy another one purely for PhysX. I am using PhysX and I have Mirrors Edge, but I can definitely say the additional glass breaking/cloth physics/volumetric smoke are not worth the cost of a separate GPU. However I guess if you really like eye candy it would be worth it to some people.
Agreed with LedHed. I'm not sure on the steps to get to work, gamer2k, but i know it does A quick post in the PhysX section should get you the answer
Fits this section better: Videocards vs General Purpose - NVIDIA Ageia PhysX, GPGPU etc. http://forums.guru3d.com/forumdisplay.php?f=22 Thread moved.
