So as Ive realised that my 7970 purchase yesterday was a mistake, I havnt received the card yet ive made a 90% decision on returning the card for a 670,

Reason 1 is that Ill get £70 back, reason 2 is because ive just watched lots of comparison videos on you tube, with and without pysic x and the diffrence is outstanding in all the graphical extras you get with nvidia cards.

The peformance is the same unless you overclock, (which I dont know jack about)

So Nvidia is the card I should have gone for, what do you guys think?

I mean ATI cards dont have anything to compare with physic x and all the other goodies you get with nvdia...
 
right, but consider this, if you get rid of the 7970 will you regret it?

we know AMD have the edge with high end resolutions and nvidia have the edge on low res. If you plan to get a 1440 - 1600p resolution It may be better on the 7970

also with nvidia physics X you can install the drivers and have the cpu draw the physics so you can use a radeon with physics X just on a nvidia card its an extra free core on the graphics card.

or a old cheap nvidia card and use that as a physics core in your bottom pcie slot

yes a very valid point, I actually run on a 2560x1440 monitor and game always on its default resolution,

It seems there are many pro,s and cons between the 2 cards, I think considering I use high resolutions, my needs outweigh nvidia cards, but I must consider all aspects, somthing i should have done before a purchase, now the warranty issue is bugging me ie on a next thread.
 
Barely any games even use PhysX (not physic x, PhysX is pronounced exactly the same as physics). Borderlands 2 is an exception in that it uses a lot of PhysX effects.

Is it worth it though? No. Also why did you buy a 7970 that was £70 more than a GTX670? A 7970 gives more performance than a 670 for less money.

a 7970 gives more performance than a low priced 680gtx overclocked.

I own both cards my 680gtx will only offset 120mhz but my 7970 does from stock to 1125mhz. thats about a 35-40% increase
 
Stick with the HD 7970 its a very nice card. I have 8 nvidia GPUs in various machines and none of them has ever seen a game with PhysX. From what I understand of it PhysX can look nice but it can also seriously affect the framerate it you are using a single GPU.
 
Keep the 7970 and run Physx off the CPU, you wont be able to set it as high as you would on Nvidia GPU's, but meh... you get effects in AMD games with the 7970 that don't work as well on Nvidia. so it's 6 and two 3's.
 
It's lame it's making ultra details or whatever setting only for certain brands of hardware.They wouldn't get away with this stuff in games on consoles imagine having an ati and nvidia xbox and certain games look way better on the nvidia xbox and worse on the ati xbox people wouldn't stand for it or let game makers get away with it.
 
Guys, there are plenty of games that use Physx.

Yes its a pain that AMD do not have acess to the tech, but then what is Nvidia to do, allow a competitor a fair playing field?

Im glad I bought my 670. I have access to everything AMD cards can do and some. Why compromise?

There isn't, there's a very small amount of games that use hardware PhysX.
 
2560x1440 isn't the sort of resolution that starts to make a difference. Yes ATI catch up with the higher resolutions but it isn't until you get to 3 monitors that you benefit from one over the other in the resolution department.

As for Physx? Yea it's good in Borderlands 2 and a couple of others. Don't listen to people saying to run it on the CPU as that's simply bad advice. It barely works on the CPU, it is designed for the GPU so running it on the CPU is very slow. At the end of the day imo there aren't enough Physx titles to warrant Nvidia over AMD if that is the only thing bringing around you indecisiveness. However, if like me you want to be sure that no matter the game you'll be able to benefit then it is worth it. I would hate a game to come out with loads of Physx affects & be stuck with an AMD card. It would bug the hell out of me.
 
If you like it you like it if you don't you don't it's that simple. No point arguing about it.

No doubt it's improved in recent years, physx effects in for example the batman games was pointless, supposed to be good in borderlands 2 but I can safely say I'm 60 hours in and can't say I've missed much.
