You are going to want a whole new system probably, for the Rift. It isn't that it's resolution matters so much for power required, it that it renders it twice, once for each eye. This is why nvidia is talking up their sli for vr stuff, because vr and stereo rendering required for it is one of the few things that sli makes sense for. The idea is one card would render for one eye, the other card would render for the other eye.

Vr is expensive to run like its designers intended.

300 watts for the 390x was a big downer for me. So once nvidia incorporates HBM, what appeal will be left? More aggressive pricing is about it

All depends on if the rumor mill is right or not. Nvida was said to be skipping 20nm and going straight to 16nm FinFET but TSMC is experiencing delays that could possible push a die shrink for nvida all the way into Q1 or Q2 2016. If AMD comes out with 20nm in 2015 and 14nm FinFET early 2016 we could see things get a lot more interesting.

Apparently someone wrote a benchmarking program for the VRAM and compared the 970 to the 980.

Nvidia needs to just give everyone a GTX 980 in exchange for their GTX 970 at no additional cost for all the trouble everyone is going through, and for ignoring everyone about a issue that is obvious.

Peep this crazy guy:

I too am an owner of the 970 chip, precisely the MSI GTX 970 "4Gb" card. I'm currently attending my second year in college and heading into the computer science, software engineering fields where I intend to major. Anyhow, Nvidia breaching their advertised chip statistics kept bothering me all day, so I paid a visit to my dads lawyer after lunch and he told me that if it does in fact turn out that the cards cannot exceed 3.5Gb or live up to the expectations of the given stats by Nvidia, there is room for a lawsuit(s).

I gave him all my info (all the agreements and such of purchase) and he'll get back to me later this week or early next week. But the important part which he emphasized several times is DO NOT UPGRADE from here on out because that will void the current agreement, meaning if Nvidia covers all the loopholes in the purchase/upgrade agreement with the next driver update, and you choose to update, you abide to the updated drivers agreement. So, if a new driver update does get released, don't instantly update. Let the pawns go first and see if the update fixes/improves the issues or if it'll be Nvidia covering their as**s.

Edit: Spared some of the details, and it is fairly late here (3AM) so forgive for typos, poor sentence formation, etc..

Found this in the geforce forums thread, posted it over in the PC Building & Parts thread but it's more appropriate here - it seems like the closest thing to a technical explanation so far?

quote:

From ocnet forum:
From the Nai's Benchmark, assuming if the allocation is caused by disabled of SMM units, and different bandwidth for each different gpus once Nai's Benchmark memory allocation reaches 2816MiBytes to 3500MiBytes range, I can only assume this is caused by the way SMM units being disabled.

Allow me to elaborate my assumption. As we know, there are four raster engines for GTX 970 and GTX 980.
Each raster engine has four SMM units. GTX 980 has full SMM units for each raster engine, so there are 16 SMM units.

GTX970 is made by disabling 3 of SMM units. What nvidia refused to told us is which one of the raster engine has its SMM unit being disabled.
I found most reviewers simply modified the high level architecture overview of GTX 980 diagram by removing one SMM unit for each three raster engine with one raster engine has four SMM unit intact.

First scenario
What if the first (or the second, third, fourth) raster engine has its 3 SMM units disabled instead of evenly spread across four raster engine?

Second scenario
Or, first raster engine has two SMM units disabled and second raster engine has one SMM unit disabled?

Oh, please do notice the memory controller diagram for each of the raster engine too. >.< If we follow the first scenario, definitely, the raster engine will not be able to make fully use of the memory controller bandwidth



64bit memory controller, total 4 memory controllers = 256 bit memory controller.
Assuming if there are 3 raster engines with each three has one SMM disabled leaving 1 raster engine with 4 SMM intact.
Mathematically ;
16 SMM = 256 bit = 4096 Mb
13 SMM = 208 bit = 3328 Mb

208 bit = effective width after disabling SMM with 256 bit being actual memory controller width

IT is hardware problem=GTX970 is 208bit card.

a) That's what I'm thinking will happen
b) Oh yes, I remember

It already seems like something in the 970 driver is generally forcing it to allocate less RAM in DirectX (although not in OpenGL) so it doesn't hit the dodgy spot, although under enough pressure it can allocate more and cause huge stutters. Seen tests where the 980 allocates more under the exact same circumstances.

So, a tad suspicious to say the least.

The issue should only manifest when moving >3.5GB of data at a time. It's not about occupying the memory, but moving it around all at once. Game engines won't be doing that though - it's an issue that'll only appear on synthetic tests.

I'm not so sure about that. It happened when I was just allocating.

BIG HEADLINE

"Stand back, Ottawan ruffian, or face my lumens!"
I'm in the 'it's still better than what I had' boat as well.

Anyone who thinks they're going to do a recall is deluding themselves. Even if this does get to a class action, the most anyone will get would likely be a discount/gift card to use on a new and hopefully non-flawed future card. They aren't going to eat as big of a dick as they did with the faulty mobile chips because the cards still *work* the vast majority of the time, and despite how many 970s they've sold, the number PALES in comparison to the amount of 7xxx/8xxxM parts that were used in OEM boxes - and OEMs are the customers nVidia *actually* cares about, hence their hoop jumping when they were caught having used inferior chipmaking methods.

It might be fixable or at least able to be mitigated by dickering around in the BIOS and then filtering the 'fix' out to the AIB companies.

That being said - remember when everyone was like "oh poo poo, the 970's like 80-85% the performance of the 980 and they're selling it for $329!!! How's *that* work?" Yeah, well...now we know.

On one hand, it really sucks that they're being super dishonest to consumers and refuse to acknowledge a problem.

On the other, a 970 with 3.5GB of VRAM is still an awesome card. I just hope they put out a driver that locks out the last 500MB on it, so that people who have the card aren't forced to balance VRAM usage in certain games.

This is really one for the parts picking thread, but if you don't want to spend a lot (around $100), and you just want a card that's decent and quiet, a Geforce 750 (or 750 Ti if you can stretch a bit) is the way to go.

I'm looking to upgrade from a GTX460 (only 768MB of RAM because I'm a moron, but it has 2x 6-pin connectors so at least my PSU is set...)

With the 960 gimped and a budget of preferably under $200...what are my options? Am I limited to only used 600-700 series stuff for nVidia? My main goal is that it not be obsolete for gaming (i.e. it's not below minimum specs) for a few years, even if I have to drop quality/resolution to nigh-unviewable levels, and I'd prefer something quiet.

e: i'm going to assume the above answer applies to me too.

Just about anything's going to be an improvement on a 460, especially with that amount of VRAM. A used 660/ti or a 760 might be something you can find cheap. I saw a used 670 on a hardware forum for $140 the other day. Alternatively you could look into a used AMD R9 280/X, and some of the new R9 285's were just dropped to $180ish with rebates since the 960's came out.

edit: I spent around $200 shipped for my 290, but I'd doubt any custom-cooled models can be found around that price now even used.

Getting eaten by the Abominable Snowman, thats a freak accident.
Are there any good products/guides that I can use/follow to help diagnose a hardware problem with a GPU?

I just moved overseas, and the computer came across via freight and I'm afraid the trip damaged the GPU. The computer works fine for normal use, but when I try to play anything that would actually hit the card, it's incredibly slow and choppy. This is a new PC I built before moving, and it worked great before the move. This weekend I'm free and want to try to fix the problem if I can, but since everything works pretty well I'm a little stuck on where I should start trying to troubleshoot the issue. I'd rather not go buy a new card, since I think I'd have to sell a kidney to afford one in Bermuda.

Check all the connectors, unplug and replug everything in. Check the fans make sure they are spinning at the proper speed. Run a CPU/GPU temp monitoring program. If the issue persists post in the Haus of tech support sub forum.
