GT430 as a dedicated PhysX card?

ZenZimZaliben · Oct 14, 2010

I have been looking into this as well. Seems the 9600GT ($50 usd) is one of the better cards to use. I guess it all comes down to amount of ROPS. Is this true?

Incorrect. I know for certain that a GTX 470 + GT 240 is better than just a GTX 470 on it's own. Also, I know for certain that a GTX 470 or HD 5850 plus a GTX 460 for PhysX makes little difference against those two same cards and a GT 240. PhysX doesn't require as much as people think. It just needs a compatible GPU.

So you've tried it.

I am a little surprised at this result.

It just needs a compatable GPU.

And a GTS450 is twice as powerfull as a GT430 (or more ) ... Making the GTS450 more futurproof and able to Follow higher end graphics card ( enven more with MultiGPU) and higher resolution.

Everything that you say is correct. I agree 100%. He have a GTX480 and i think a GTS450 is more suited to follow this "Badass card".

I have a Question, i have a ASRock X58 Extreme3 MB with 2x PCI-E 2.0 16x slots and 1x 4x slot, and i have 2x Geforce GTX 460 1GB in SLI, now can i use a Geforce GT 430 in my PCI-E 2.0 4x Port as PhysX Card?

newtekie1 · Nov 25, 2010

Yes. Though you probably won't notice any difference if you add a dedicated PhysX card, the two GTX460 1GB cards can handle the minor PhysX load without any real performance hit.

Thank you newtekie1 i want to know because i want to play Metro 2033 and even with 2x Geforce GTX 460 1GB you get slow downs when you enable PhysX in the game, and if i use a Geforce GT 430 as PhysX Card the game has to run good on very High.

It will cost my only € 65,-.

What do you think?

Would an 8800GS 384MB be any good as a PhysX card? Would be alongside a GTX 580.

Yeah, you'd think that, but it doesn't help. I've tested it with my GTX470 and my SLI GTX460s. Adding a dedicated PhysX card to the GTX400 cards just doesn't do anything. It really takes next to no GPU power to run PhysX, so the slowdown you are experiencing is almost certainly caused by the extra graphical rendering power required to render all the extra 3D particles created by the PhysX effects.

The 8800GS 384MB is one of my favorite PhysX cards, it works wonderfully. However, paired with a GTX580 would be useless for the reasons I've already stated.

OK thanks

Mafia II never used more than 45% of my 8800 GT! I played it @ 5992x1080 with the rig in my specs. So I agree that GT240 is enough for PhysX.
