Want some input on upgrade.

post #1 of 33
Thread Starter 
Im looking into upgrading my video cards. Right now I have to 6970s Xfired and OC'd as high as you can get it in CCC. The last few games I have played (borderlands 2, hitman and farcry 3) are having trouble keeping up on ultra/high settings. They are playable, just not as smooth as I would like them to be.
So I was looking into upgrading and maybe going with a single card solution that I xfire latter. At the high end I see my options are the 680 or the 7970 GHz editions. I have tried reading "reviews" and "benchmarks" but bench marks don't always reflect reality and reviews are pretty much just written by fanbois these days.
Has anyone played with both or seen both in action enough to recommend one over the other? Any input would be appreciated, money is not really an issue so I am really just concerned with performance.
The rig in my sig is what its going in but im running win 8 now.

2x6970s roughly equal 1x7970/680, roughly. It will be a slight upgrade for you but then again you will have one less card to deal with.

Between the 680 and 7970, the 7970 is obviously faster clock for clock. But there are other considerations than just fps. The 680 has cuda and physx, if that's a priority then the choice would be obvious I think? I run both cards and I like them both for different reasons, however the setups that I have are vastly different too.

Have you considered one of the dual core cards? I know the 690 is readily available, not sure about the 7990 though.

What does cuda and phsx do? I have never had an Nvidia card but I have heard of that.

I was looking into those, they don't overclock as high as regular cards xfired.

They're proprietary standards that Nv developed to rope people into buying their cards? Haha, I kid, or maybe not? laugher.gif

Is that what makes games that have that Nvidia "the way its meant to be played" logo thing during the startup run better?

That is just brand sponsorship, er well that's all it's supposed to be. wink.gif

Cuda is a standard for accelerated processing using the GPU, for ex. using Photoshop. There is an open standard which is what AMD uses. Physx is a special chip more or less that handles special eye candy using physics, but the game must be developed to use Physx. There is an open standard. Guess which AMD uses? Some ppl like it, some not so much. I don't like it because it makes the system crawl when it is actually enabled, ie. it incurs a large performance hit.

PhysX will make Borderlands 2 debris a million times more exciting, as well as realistic cloth and all that jazz. The other 2 games you mentioned don't use it.

CUDA is a compute standard which makes Nvidia cards great for Folding and other CUDA optimized programs. Not really important for gaming (plays a role in PhysX though I believe.)

Both cards are going to offer relatively similar performance. The easiest way to decide is "Do I want mad PhysX/Folding superiority?" If not, go AMD.

Edit: I obviously simplified a lot to give the gist of things. I may be wrong about the Folding thing, I thought Nvidia cards dominated Folding but I may be misinformed.

Im sorry I did not understand that last part. PhysX makes the system crawl or the open one?
