GTX580 with 8800GTX for Physx

post #1 of 21
Thread Starter 
Hey guys.. I'm wondering if I will gain performance by using my 8800gtx for physx card?? Or instead it will bottleneck my 580 because of the slower gpu... any comments will be appreciated!

The 8800GTX doesn't SLI with it...it actually just takes load OFF the 580 in which case you're just helping yourself...just make sure you go to the Nvidia control panel -> SLI and PhysX tab...then make sure you have the 8800GTX dedicated to PhysX instead of the CPU or the 580. Nothing but performance gains in games that support PhysX! have fun

Not worth the effort imo, so few games that use PhysX and the ones that do you get the meh! factor.

I ripped my 2nd older card out and flogged it off, all it was doing is chewing power.

no you don't.....
I maxed out that game lag free with physx on high without a dedicated physx card
I set physx to auto in the nvidia control panel

i can't help but think its a complete waste of time and waste of electricity a 580 gtx can handle it just fine on it's own

I would be keen to see some benches with this setup i have a spare 8800 gtx lying around i could try this when i get my new gtx 570

Wouldnt use to for physx, i saw a russian review on using a gtx480 with a 9800gtx and it actually got worse performance. It will happen to you with your 8800gtx
