NVIDIA Geforce 260 GTX + HIS Radeon HD 6950 - PhysX dedicated?

post #1 of 12
Thread Starter 
Hi,

I'm considering using my HIS Radeon HD 6950 card as my primary gfx card, but using a GTX 260 card from NVIDIA to do the PhysX work. How would I go on doing this? Just connect the card and play?

Also, slightly offtopic, would a Chieftec 550W PSU power both cards?

Cheers,
Michael

not sure about the PhysX but newegg's psu calculator recommends 793 watts with a athalon IIx4 dvd combo drive & high end mobo
without your other sys specs I had to guess but the cards require around 200 watts each

a quality 750watt unit is way more than enough, physic doesn't use as much power as if it was used as an actual graphics card

Can you even use an ATI card with an Nvidia card as Physx? I didn't know that was possible... :O

Neweggs PSU calc is useless, im running a GTX 275 SC and GTX 470 and a phenom 2 X4 OC on a 650w with PLENTY of room to spare. Plus my 4 HDD's and 2 DVD-RW's.

But no a 550w woukldnt work bery well, or if it did it would be a close call.

You can... You need to use the driver hack....

Though let me be the first of many and point out a dedicated physx GPU is pretty much a waste of time.. So few games support it, its not worth it...

I'm not sure of the quality of that particular Chieftec unit, but it's likely not exceptional.

A good 550w PSU would probably power the setup, but it would be cutting things closer than I would be comfortable with.

I concur.

Unless there is a specific game or games you have in mind that are significantly better with PhysX, don't bother.

Quiet.

@OP
It can be done.
It is worth it if its just going to be sitting idle, you may want to look into Folding@Home for Overclock.net (team 37726).

Could you explain how I should proceed with the "configuration" of the cards?

Offtopic: I've got a spare server (Amd phenom 965 BE, oc'ed to 4GHz, it was my old gamer), should I consider using that one for Folding@Home?
