Sorry I haven't been following this issue 24/7, I guess I'm just too stupid.
Well maybe you should follow the issue you comment on?
And it's not only you I mean when I'm saying that the stupidity of comments on the matter is through the roof here.
People are seriously exchanging a better performing, quieter and cooler card for a worse one because it has 0.5 GB more RAM? Even though up until now there is no solid evidence that these additional fast 0.5 GBs help anywhere at all. The only resolution where 290X goes ahead of 970 in benchmarks is 4K and both cards aren't up to this job since there won't be even 30 fps there even in today's titles which consume less than 3 GBs of VRAM.
People are planning to game in 1080p and they opt for a slower card with 4GBs instead of a faster card with 4 GBs (yeah, 970 still have 4 GBs RAM and it can use them all and not having them would actually be worse for several reasons).
People are opting for a 980 which is like 20% faster for 50% more money even though there is no evidence of any sort that 4 GBs won't ran out at the same time as 3.5 GBs will or that both cards simply won't be able to handle the shader load.
People are posting videos with stuttering in SLI setups saying that this is 970s fault even though anyone who ever had any kind of SLI / CF config knows that these are prone to stuttering and microstuttering no matter what number of VRAM the cards have.
People seem to be unable to read when NV's representative clearly says that the driver's memory allocation algorithms are heuristic meaning that they are generic and will work with any application requesting access. Sure there's always room for improvement. AMD have churn out more than twice a driver which significantly improved their memory allocation on cards which did not have different performing memory on them. NV have made the same several times. What they will be doing for 970 with the drivers does not differ at all from what both of them have been doing for ages.
People are saying that performance is irrelevant and what matters is that NV lied to us - NV doesn't have to tell us jack shit, it's their decision to disclose any information on the underlying architecture. We have very limited number of ways to confirm if what they're telling us is true at all. Same goes for AMD, Intel, Apple, etc. The only thing that matters is the consumer qualities of a product, not some random numbers the companies are throwing at us.
Now some guy have his display flickering - that's because of 970s memory partitioning of course! For fucks sake...
Anyway, I'm a (disappointed) owner of a 970, and while it's working great most of the time, I've noticed some random stutter when I use DSR at 4K on old games, I thought that shouldn't happen (being old games), but now I think I know the reason...
You've pushed the card to 4K resolution and it stutters because of the memory config? Did you try to find out how the same game at the same settings perform on a 980?
There's too much assuming going on over that issue.
