Dedicated phsyx graphic card

[stantheman123]

I got a 7970ghz

Im thinking of a phsyx card under $100 however if more is needed i can go

For under 100 theres a gt 640 however i do not know how good it is for that

Have you looked into the fun and games you are going to have getting that setup to work or are you just expecting to plug and play?

only selected few games support physix so i think its a waste of money. the only recent game i played that used this technology was mafia 2 and with physix you can choose for it to be done either on the video card which will lower your total fps or the processor...i overclocked my processor from 3.4 to 4.8 and set the physix to be done on the cpu and boom max physix max graphics with no additional hardware needed

I thought it would be easy to make it work wouldn't it? Trade my 7970 ghz for a 680? I don't think I can do that well it would cost the same in the end since 680 is $100 bucks more than the 7970. Wouldn't a 7970 ghz+ gtx 650 perform better?

No as BigMack70 said, you are going to have to jump through a few hoops due to Nvidia locking AMD cards out a couple of years ago. Personally I think you can thank a certain R. Huddy for that although I'm sure the AMD/ATi faithful would disagree. :lol:

 

[stanistheman]

Hmm well fair enough thanks a lot guys. I guess no dedicated physx for me. Ill just stick with my 7970ghz and get 7xx series of nvidia

PhysX is one of those things that ya don't miss until ya turn it off.

Turning on PhysX isn't necessary for gameplay, and you'll never miss it if you don't see the effects. However, when PhysX is enabled, it adds superlative nuances and really creates some “wow” moments. The chunky explosions, cloth effects, paper, fog, and environmental detail enhancements are very cool.

Once hardware-accelerated PhysX is enabled, this is another matter entirely, and those of you who want the best high-resolution PhysX performance will need to consider an Nvidia graphics card more powerful than the GeForce GTX 260 or a dedicated PhysX card such as the GeForce GT 220. There is a high price to pay for PhysX performance, but I have to admit that the eye candy is a lot of fun to watch. Once you've turned it on, it's not something you'll turn off if your hardware can handle it.

Of course, nowadays that additional expense of a dedicated card is about $50

I'd also say that, having been used to PhysX, I fully expected a "yawn" moment when I played Batman AC .... and let me say first that I do not enjoy 3D movies ..... but I found that the when I played the game on my son's box in 3D on a 120 Hz monitor, the comparison between playing with PhysX and 3D on and off was like b & w TV versus color.

If ya wanna judge for yaself, see a ON / OFF video comparison here:

As far as CPU based PhysX, that's like saying a McDonald's Burger and a Kobe Beef Steak are the same cause they are both meat.

Well the reason I was wondering is because on the metro 2033 benchmarks t 7970ghz with everything maxed 1920x1080 DOF off I got avrg 27fps and my mate did the same test got 39fps I thought the 7970ghz was a faster card or atleast on par. Are my results correct?

What card/system was your mate using?

 

[stanistheman]

He has a asus gtx 680 direct cu. and a core i7 2600k stock neither are overclocked. And i got a amd 6300 4.5ghz and a 7970xfx ghz.

So do you believe the CPU is making that much of a difference? Or are you now beginning to question the validity "advice" given out by some as to which is the faster/better card?

 

[stanistheman]

I'm just confused. I mean I don't regret my purchase I paid 417 for my card my friend paid 565. Since I'm in Australia. I thought it was my drivers but I'm running the latest 13.1.... However I don't see my 7970ghz out performing my friends 680. This is a good experience for me. Cant always trust others and benchmarks on the Internet..

 

[stanistheman]

From 27 to 57

 

[stanistheman]

Thanks a lot guys and mack really clears things up.

The way I would approach the need for a dedicated Physx card would to look at it from this perspective. When a game comes out the current series of GPU's will have a hard time show casing the Physx on high the higher end cards in most cases can handle it but your frames will suffer. Now if you are a generation after that most games typically will give you no fuss. For example the GTX500 series of cards were out for Batman Arkham City the cards had a hard time with Physx on high as well as DX11 as it was a newer tech. However with the implementation of the 600 series both of those issues were tossed aside.

But with all that said you are using a 7970 ghz edition and the only real way to utilize physx with a nvidia GPU and your amd card to my understanding is to use hacked drivers.

And while I agree with most games being able to be ran off the CPU with phsyx enabled you get far superior performance with a graphics card rendering the graphics real time for you. If you want a game in all its glory it will be very hard to do on a CPU. I would imagine if you could use advanced physx in the new Metro game it would destroy a CPU performance wise.

PhysX is CPU based not GPU based, physx is just a physics engine, much like havok.

 

[bigshootr8]

If you have a AMD card physx is forced onto the CPU. If you have a Nvidia card it is taken care of by the card.

 

[Mousemonkey]

PhysX is CPU based not GPU based, physx is just a physics engine, much like havok.

Actually it runs better on a GPU than a CPU so although it will run on a CPU it isn't CPU based and never was.

 

[bigshootr8]

Indeed however in some games like mentioned above with Batman Arkham City you can not run physx on a AMD card you need a Nvidia card it greys it out.

 

[bigshootr8]

Dang man you are balling at 10-15 frames a second haha! Yea my 5770 when I bought the game would not let me turn it on. They may have changed the settings since then I remember then I had to turn on DX11 to use it and my 5770 crumbled with DX11 turned on.

And yes I would look at that list if you don't play any of those games I see no reason for it. And even then its a personal taste do you like the effects or not. I feel it adds elements to the games I play (Borderlands 2, Batman AA, AC, and Metro 2033) however this may be different for you.

My theory is this if you are not going to use this for all your games or a good chunk then there is no reason to get a dedicated physx card.

 

[stanistheman]

Lol the funny thing is I've recently only been playing metro 2033 ad batman Arkham city and I just downloaded borderlands 2 haha. But idk f that's worth trading in my 7970gjz and flopping down $100 for a 680. Maybe I should of kept my gtx 590 but it was annoying when games didn't support multi gpus and the heat was insane. Nice fps mack 1440pp as well thats pretty beastly. My xfx hits 70-72c so I don't think crossfire is a option haha

 

[bigshootr8]

Well with Borderlands 2 its more immersed physx and I guess the same could be said with Batman however with Metro you aren't missing much. It isn't worth it honestly you have a beast card stick with it. If you can play it and not care now you'll be fine.

 

[stanistheman]

Yea I was just hoping that with physx games I could put It maybe on my cpu but I should of Got a i5 for that. Oh well. Your right ill just keep my 7970ghz. It's a fine card for gaming. I really appreciate your input guys. It's really cool to have opinions from people with good knowledge about computers. I thought it would be plug and play with a dedicated phsyx card. But hey learnt something new. Thanks guys.

 

[bigshootr8]

Hey at least I know you have good taste in games Happy gaming man.
