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.

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 see...I just realized that Mafia II is the only game that needs physx.. all others dont.. like mw2.. black ops.. bc2.. so i guess i'll just use it somewhere else... thx for the info...

Read through this short thread (http://www.overclock.net/nvidia/9077...gtx-580-a.html). I suggest you to keep it for Physx as it will help, a little more in this game and a little less in another game. But it will contribute as a Physx card.

And, it is not that you have to shell out extra money to buy a new card. It is already in your possession and so, at least, try it out before disposing it.

''Popular'' games that use Physx: Mafia II, Batman AA, Metro 2033, Mirror's edge, Cryostasis.

I can speak from my own experience in a game like Mafia II that really utilizes PhysX it really helped me. I have a 470 and used my BFG 8800GTX as a physX card, I saw about a 10 fps jump in Mafia II. In other games that use PhysX like Cryostasis I also saw a nice improvement. Of course both of these games are physx heavy (and Cryostasis pretty much just plain sucks) so your gains will vary.

it should also be noted that you have a 580 so you might not need it to begin with. In my case though the BFG had basically no resale value so I just set it up to see what would happen and I was impressed. With that said though I wouldnt have gone out of my way to buy a dedicated physx card.

Also if you run a second monitor for temps monitoring things like that. You could use the second card to run your second monitor. Which I find lowers the temps of my primary card by 10 degrees C. And it sure does look cool as well.

Thanks for the infos guys... I'll probably going to use the card for folding, just like what terraprime said...since only my parents will use my other rig, and it wouldnt hurt at all when they're just watching news and surfing the web, stuffs like that... doing some contribution does make me sleep better at night tho

Using extra electricity needlessly and contributing to global warming is contributing how?

Hock the card off on ebay to someone that will appreciate it, and chuck the cash at a charity to feed hungry African Children, that's contributing
