Why are you quoting a regular poster from another forum on this forum? If you like what he said, respond there perhaps?
Why are you posting in here as you do not appear to have a 970?
Too many fan boys with no real knowledge assuring people that the 970 does not have a problem when even Nvidia themselves are not doing this.
No matter the resolution, using a 970 for CUDA, gamming or any other Vram intensive workload, whether you use Windows, Linux(includes upcoming SteamOS) or OS X you will run into the Vram issue eventually. At best the result will be micro stutter / poor CUDA performance without specific patches. At worst the result becomes single FPS while gaming. With so many ports coming from console we my very well find that 4GB is the new standard for smooth PC gaming due to preloading textures enhanced by DX 12's memory management. The 970 has only 3.5GB of high performance Vram with a crippled 0.5GB tagged on that cannot be accessed at the same time. I just can't imagine developers coding specifically to work around the 970s issue without Nvidia's finance.
AMD option for now is the 290s. Hard to justify when the next launch is so close. Or the unknown wait for the 3xx series. Mantle looked fantastic when 1st announced yet has failed to reach a must have position. I would have expected Mantle to running on both Linux and PS4 by now with OS X in the pipeline. Intel should be on board with Mantle by now if they ever were going to. True Audio is something that makes my ears
***** up as my eye sight is not so great. Yet I can't remember hearing of this tech since Lichdom released perhaps 6 months ago? On the upside AMD has VESA Adaptive Sync support and so will my next monitor purchase.
Nvidia option would be to upgrade to the 980. GameWorks appears to be on a roll and it does add some very nice visuals when developers can't be bothered to add their own. PhysX has always been a bit of a lame duck and not something I need due to other software based options but still adds a nice check box. Shield as far as I can tell has been a failure. G-Sync has always made me smile along with MCA if you are old enough to remember IBM's folly, good ideas badly implemented. No support for VESA Adaptive Sync stops me purchasing a 980 right now.
I am not surprised at low return rates so far. Many customers will not understand the issue with the 970 and falsely believe it will not affect them. More will simply not be aware that an issue exists. I myself have not had any contact from OcUK informing me of an offer of refund while it is obvious to me that this product breaks our sale of goods act in the UK. Even more strange that retailers are continuing to sell this product without a warning.
970 looked like a great card at launch, now not so much. Continued silence from Nvidia is not helping anyone.
Sorry for the long ramblings. Fan boys misleading people just irritate.
