Which card for PhysX

[ghutchison14078]

At a guess thats what the OP is buying a physx card for. It would be pointless them buying an 8800gt and not being able to run physx maxed out. I dont think they would be best pleased, I know I wouldn't.

I would say to be on the safe side go for a physx card with the power of a 260gtx.

Think I'm gonna go for this.

Either find a decent 260 gtx second hand or get the ocuk value one. This should my system enough oomph to run physx at high levels!

cheers for the input guys!!!!

Does the memory matter? Have a 256mb 8800GT I was thinking about messing about with.
Also have a 1gb 9800GT but in my mind, that is blatant overkill.

No, memory doesn't matter, PhysX doesn't load any textures. Processor count and core speed is what matters only in this case.

Imo, Nvidia is telling porkies to cash in.

Yeap.

Seriously, you would be better spending the money on something a little more worthwhile. Maybe an SDD or quality sound card.

Like people care. It's NVIDIA® PhysX®, gotta have it, noob!

Sure, why not waste £100 and increase electricity bills, it's worth it.

I doubt Nvidia will walk away from Physx. They have invested too much money into it. There will be more physx games in the future. How many is anyone's guess.

One magic video by Nvidia a year, me thinks. Gotta keep the brand alive, right?

There is definitely allot of marketing strategy behind physx and there is no reason why a cpu couldn't do it. Nvidia will use physx as much as possible to get people to buy their cards, its as simple as that. At least they are now allowing ATI owners to use nvidia cards for physx, I thought it was wrong when they closed that off.

I think this topic on physx will keep on going until the format is dead or open source for everyone to use.

 

[Mr Krugga]

Do they really allow ATI users to use PhysX? I thought there's still need to use modded drivers?

Another classic statement, Increase electricity bills. You do know all the bits in your sig that you have overclocked increase your electricity bill. Or do you only try and use this arguement for your anti Nvidia agenda ?

Nvidia closed the loop a while ago and only recently posted beta drivers which will let ATI owners use physx with their set ups. I believe nvidia have said that they wont released WHQL drivers that will let ATI owners use physx only Beta ones.

Those betas were retracted & future beta drivers will not allow it.

Oh really. I thought Nvidia were just going to leave physx compatibility with their beta drivers and not offer any support.

These guys really know how to shoot themselves in the foot. If they let ATI owners use nvidia cards for physx think how many more cards they will sell and how it would push the physx platform forward. Closing this off is only hurting their sales.

Stupid is one word that comes to mind.

Wtf do you mean? It doesn't matter how and what I overclock because I can clearly see the benefits of it. PhysX dedicated cards will run maxed out at their cores using the power only for these effects. Do you get it now?

I've just sold my 8800GT. I was going to keep it as a physx card but found it didn't make enough of an improvement to justify the money and electricity use (about an extra 40 watts at idle).

Here is the difference it made when running the benchmark in Batman Arkham Asylum - 1920x1200 all settings on max, physx on high....



As you can see (I hope) the main GPU usage is slightly lower with separate physx, but the 8800GT is really only running at about 30% at most.

min / max /avg results were
10 28 16 = CPU
20 60 49 = just 460GTX
27 60 53 = 460GTX + 8800GT

 

[RavenXXX2]

^^ yeah it's a scam, purposely not optimized.

 

[ed79]

The point I may not have made very well above is that in Batman an 8800GT is only being used ~30% and so that card has a fair amount of headroom.

Up until a few days ago I was using a 9800GTX for dedicated PhysX.

And then by accident I realised that running PhysX on my main card (GTX480) gave me almost identical results.

9800GTX is now sitting in my spare rig.

Indeed & is case of mine all mine getting in the way more sales of cards as physx to people that use other GPUs.

NVs lock is that Physx is so good that its going to win more sales anyway & that people will want it so bad that they will drop the other GPU & buy 2 NV cards instead 1 main & low for physx.

 

[coughs]

Where can I get a 2nd hand 9800GTX as I want a good enough card for PhysX?

 

[jigger]

Zee bay ?

 

[gadget^]

now i have the 480 AMP Zotac was wondering what to do with GTX285 its worth £100-£140 or should i keep it for now to use as a dedicated PhysX card ?

 

[Stonedofmoo]

I'd wait for the midrange/low 400 series cards. They're bound to be good at PhysX without breaking the bank. Heck until Mafia came along I'd read plenty of guides that said a Geforce 220/240 was more than enough to run PhysX titles.

 

[Shaftydude]

Has any PC websites ever done any benchmarks with and without a PhysX dedicated card? This would be the best way to see how much extra fps you actually get using a PhysX dedicated card for games like Mirrors Edge, Batman Arkham Asylum and Mafia instead of guessing GPU usage.
