Hello, i hope someone still watches this thread.. would this work with a Tripple Xfire setup(ofc having 4 PCIe slots) for example 3 x 5870 and a Nvidia card? like a 260 or a 440 or any cheap Nvidia solution? cheers for your time

It is only worth it if you are playing a game or benchmarking that is written to use Agea PhysX, if you are not then there will be no benefit to you at all. Breaking it down further, most benchmark sites, such as FutureMark, do not accept Vantage run scores that has PPU (PhysX Processing Unit) enabled so, you should really only entertain the idea of doing a hybrid-PhysX setup if you are going to use it for gaming.

Listing of nVidia's Agea PhysX games can be found here.

I know its not really worth it, but i like to do stupid/new stuff with my computer, and i do game alot, but its mostly because i feel its a "new thing" which is also fairly non-expensive(i might even have found a 9800gtx i can use heh) my question was more about if tri Xfire in anyway gets crippled or less performance if id add a 9800GTX for example, thanks for the reply!

You would loose a little but you will loose some any ways because trifire will have the pcie lane to 8x8x8 or 16x8x8 depending on mother board I do it and i would only recomend if you have the graphics cards> I would not spend any money on this set up. its fun but not really worth it =. most game coming out are not using Agea physx also there is a thread here that shows the lost of some graphics with a hybrid physx card but gain alot on physx

My lanes do not drop down from x16 with my 9800GT and both of my 5970's installed. I think that is because the 9800GT is not being used to render 3D, it is only being used for PPU, so I don't think that he will have that problem kleetus, but then again it could just be my setup.

Simond88, if you have a spare nVidia card laying around that supports Agea PhysX, or can barrow one, cool.....give it a shot and see how it works out for you. The stronger the card the better it will handle the PhysX processing (more particles) but it will not increase your FPS at all.....actually it will decrease it a tad, but you will see the difference in the games visuals a bit. If you try it let us know how it turns out for ya.

my asus CHF4 goes to a 16x8x8 but i dont think its that much of a lost like you said
I think if you put it in the x4 lane this wouldnt change the 16x16 and for physx card it is plenty.
