I was on ibuypower configuring a PC for the hell of it and i saw the option for a 3rd card (Physx card ) I understand its suppose to add the extra boost to games with high details and imagery. But what i dont understand is can you get 2xGTX 590/580 and a different model 590/580 physx card and TRI-SLI them. Im not sure if it was there error to allow that to happen.

2nd question is - Can you Tri-Sli GTX590s, i know you can do them to 580s

Teach me something,

Thanks :o
 
Some people run a dedicated card for physx. However it's not really necessary as only about 2 games actually take advantage of this.

590's are a dual chip card, so no you can't run tri sli as this would actually be 6 way sli.

Quite a few more than two.

If you have a good main card like a 570 or 580, and a spare 6pin connector, a GTS 450 makes an awesome PhysX card.

ic, so you can have 2x 590s and 1x580 physx card ? or 2x570 and a Physx ? and connect them all through a bridge port

i typed into newegg physx and i got this

There are a lot of combinations that you can have with a physx card. as far as I know the restrictions are that you can have as many cards in SLI as the chip will allow. So for some cards it will be 2 way SLI and for others it can go up to 4 way SLI. You use the SLI setup for graphics only and have the physx card extra (not hooked in with an SLI bridge.) So if I have this right you could have 4 GTX 580s (or 2 590s) and a dedicated GTX 560 for physx.

Physx is just a bonus that you get with nVidia cards. The one that you linked is just stating that you can run physx with that card. But really all Current nVidia cards can run it.

If I have any of that wrong please correct me.
 
thankyou ^! i have learned alot from all of your guys but that was another question that just got answered (PhysX card doesnt have to be bridged) gotcha :D thanks !
 
No two cards HAVE to be bridged.

They can either run independently to each other, allowing for processing on each card separately and more total displays, or can run together without a bridge.

However, running cards together without a bridge can cause problems. Speed will most probably be reduced, not just because you lose that data path, but also because more errors will occur, so the scaling % (the % performance gain from having 2 or more cards per card over a single GPU) will be reduced too.

You do not need a dedicated Physx card to have Physx. All Nvidia cards from the 8000 series and later (ie 8000, 9000, 200, 400, 500 series) have Physx. Just by having such a card, you will be able to utilise Physx in applications that use it.

Note - in applications that use it. If a game does not feature Physx and is not programmed to use it, it won't have a single bit of difference if your card has, or does not have Physx, so rather than saying "This card has Physx, so will be better", first look at games you will be playing, and see if they have the feature. If they don't, then Physx isn't exactly a selling point to you, it is instead just marketing jargon that actually means nothing at all
