8GB GTX 970 price?

If you are so smart perhaps we can do this the other way round.

Let us pretend I am the one with the problem that my 4 x 980s don't perform as well as my 4 Titans or 290Xs when running Heaven 4 @4K using different PCI-E settings (1.0, 2.0 and 3.0).

Can you suggest anything I can do to get my 980s to perform as well as the other setups.

What do you recommend ?

Not so easy now you can not waffle is it.:D

It's called drivers my friend, I've already made a thread about it in the Nvdia forums, 4k killing GPU fuseage and thus SLI.

The 290 and 700 series weren't exactly amazing at 4k at first was they?

Sell all your GPU's and get a PS4, makes life so much easier and money in your pockets :cool:

Actually both the Titans and 290Xs were very good from day one, I got both on launch day.

Drivers have nothing to do with how a card works with different PCI-E standards in the same PC where only the PCI-E setting gets changed in the bios.

There is also nothing wrong with SLI in the 9 series either. The problem is that they are hardware limited when it comes to 4K, this is something that will be addressed when NV release the big max Titans and you know what the scaling will be top notch @4K with excellent quad SLI from day one.
 
The problem with threads like these. is that the opening poster asks an innocent question and we here on the forum, well most of us like a good discussion (ahem) and will look out for people making comments that we can disagree with. Maybe not intentionally, but invariably it degrades into that sort of discussion (ahem) that we all love so much. :)

Anyway to answer the opening posters question.

There have been no announcements of 8GB Nvidia cards as of yet. Myself I am sure there will be and I would expect them to follow the currant market trend of being £45- £85 dearer than the 4Gb equivalents.
 
Kaapstand can't desolder a load of the chips to simulate a narrower bus width, he's trying to limit the cards in other ways. PCIe link speed probably isn't the most accurate comparison but how else to do it?

Meanwhile, you assert that a 980/970 8GB will be fine as "not a lot of data is shifted per frame". So, seeing as according to you the 980's obviously have enough VRAM bandwidth to cope with 8GB of textures etc, they must have VRAM bandwidth to spare! Let's try this experiment...

980 4GB 2 way SLI fire strike Ultra, 1354/7600:

5807 overall, 6068 gfx.
http://www.3dmark.com/3dm/4880180

980 4GB 2 way SLI fire strike Ultra, 1354/6000. Reduced memory bandwidth is equivalent to trying to stuff twice as much data down the same bandwidth. This is a ~24% reduction in bandwidth so I think I'm being generous.

5576 overall, 5835 gfx.
http://www.3dmark.com/3dm/4880255

To me, this shows that there is a measurable performance impact in reducing the memory bandwidth while using the same amount of vram. It seems logical to conclude that doubling the amount of data with the same bandwidth, there will be a bigger impact than with my 24% change in bandwidth.
 
So it looks like as long as the extra 4GB is used for caching the 980 would be no different to what it is now, but if the game is actually throwing around more than 4GBs worth of data at a time then its going to be an issue.

Interesting that AMD are churning out 8gb cards whilst Nvidia only did the 6gb 780ti's and even their flagship 980s only have 4gb.

Well actually titans and titan blacks are 6GB ,There was a limited 780(non ti) 6GB run aswell, 780ti's are only 3gb

Ah didn't realise it was the vanilla 780 and not the Ti. Still interesting though that Nvidia seem to be trailing AMD with VRAM sizes.

Tis true. There also weren't any stock versions of the 780 with 6gb so it was a bit of a bummer, especially as 4k requires SLI and blower coolers are king for it.

Tis why I went with Titans. I LOL at small memory buses :D

I also didn't waste my money on a high priced mid range card, then be all disappointed when Nvidia release the actual high end card and not the pretend one.

Made that mistake with GTX 670s.

Same here and I'm actually appreciating the 290x now the day's are getting colder, I've got a pair of 14 cm fans blowing it's heat straight at my feet as we speak :)

Nvidia already told Gibbo they have no plans of releasing an 8GB 970/980, Anything you hear is complete made up lies by people with too much time on their hands.

That's a shame, the reason I asked is because there's lots of sites reporting that an 8GB version is inc in a month or two, I didn't know those sites were lying and I was planning to buy a 970 in January so would have gone for the 8GB version.
