460gtx or 6850? PhysX?

post #1 of 28
Thread Starter 
Wat should I get 460gtx or 6850?

What exactly is PhysX?

Do both cards have it?

What are the pros and cons of both cards?

I can't run my 9600gt as a PysX car as my MoBo is poo.

Well Physx is an Nvidia ONLY technology.. there are only a handful of games that use it.. and as far as I know you can use an ATI card as your primary card and then use an Nvidia card for the physx if you want to.

http://www.nvidia.com/object/physx_new.html

So to answer your question only the GTX 460 will have physx capabilities and the ATI card won't. As for which card is better I will leave that to other people to debate.

How does the GTX 460 HDMI 768MB compare to the 1G?

I am leaning towards the 6850...even though many say the 460 is better....
I think onve ore driver come out for the 6850, it would win looking at the specs
6850
has
Memory
Memory acceleration
Memory bandwidth
Memory capacity1GB
Memory interface256-bit
Memory speed 4,000 Mhz
Memory typeGDDR5
Processor
Processor speed 790 Mhz

460 gtx

Memory accelerationNo
Memory bandwidth 115.2 GB/s
Memory capacity1GB
Memory interface256-bit
Memory speed 3,600 Mhz
Memory typeGDDR5

Processor speed 715 Mhz

close i know...thats why it is so hard to make up my mind...

Get whichever of the two cards are cheaper, from a manufacturer you trust (I personally would avoid XFX, anything else should be fine though).

PhysX is a marketing gimmick from Nvidia. It's just extra fancy particle affects that the GPU processes...but ONLY with an Nvidia video card.

No, only the Nvidia card can do PhysX. You can use an ATI / AMD primary card, and an Nvidia PhysX card though (assuming 2x PCIe lanes).

Both of the cards that you have chosen perform VERY similarly in both single and dual GPU configurations. The only difference is the brand on them, and PhysX support (which really isn't worth basing your decision over).

The GTX460 won't be enough to handle PhysX and doing gaming at the same time anyway for most PhysX games. So its not worth it to base your decision on PhysX alone. It is neat to have the option to have those effects on or off. But my single GTX470 couldn't handle Mafia II with full PhysX. Same with Just Cause 2. Added the GT240 for PhysX and driving my other monitor....all is fine now.

XFX is a great company. every1 started to hate them after the 4890 incident.
ive owned XFX 8800GT, good patch 4890, bad batch 4890 and 5830 and they all worked fine (except for bad batch. i RMA'd that sukka and they sent me a 5830 tongue.gif)

PhysX is a gimmick. ive used it b4 and its not really worth spending money for a physX GPU. besides, Source, Havok and CryEngine3 have much better physics.
i say go with the 6850. they scale way better than the 460 in CF and are quieter, cooler and use less power too.

You made my decision much more easier over nvidia and ati! thanks!

Ok dude...nVidia has more stable drivers for their card..well from experience anyways. Their nV control panel is so user friendly as you can set the video settings for each application with ease.

PhysX is only available for the nVidia cards, but you can have PhysX with an ATI card but you will have to do more work in terms of setting up the cards to work properly. Nvidia has PhysX right out of the box. Basically PhysX creates a more visually appealing gaming environment...particles, cloth movements...things like that. Here's a comparison with PhysX and no PhysX:

To me this is a no brainier. I've used both nVidia and ATI and I have to say nVidia just seems to have a better quality product.

Nvidia physx is just hokey gaussian particle junk and it just doesn't look right or work right.
Physics is a more encompasing system that is a bit harder and developing slower but it doesn't leave with you I just licked a dirty rock taste in your mouth when you see the effects.
Nvidia's physx is simply light particle effects that people have been doing in spell effects for years. It doesn't even make nice looking smoke though and it's horrible at breaking up structures like building destruction.
Physics will run on cpu or will run on opencl once it's more developed.

That's so bias....let the visuals decide...take a look at the comparison video's OP. The smoke effects is far from "horrible".

ok so if nvidia divers work better, let me know if they dont flash durring shut down. I hate how my gtx295 does that, and other lower nvida cards. does any one else expirience how the nvidia cards flash at shutdown, and do not look as vivid and sharp as ati drivers, for the win-7 UI.? thanks!
