    You know what, I give up. If you want to believe that a GPU accessing system RAM is faster than accessing onboard RAM then go right ahead, but doesn't that sort of shoot down the rest of your argument?

    hello fender I don't have any issues with mine ? so really its a lot of fuss about nothing still as fast as the day I got them and honestly I would not change back to the 290x with all the issues I had with them let alone the noise they even use to heat my whole room up lol while munching at my PSU you need a big psu to run them 290x's with issues. im sticking to my wise choice as im happy with my purchase.

    edit

    someone should look through the guru3d forum and add up how many people had issues with spiking etc back in September until now I bet there was a spike when the kiddies forums started to beat there war drums

    I'm not going to pretend I know the details. I have no idea how the 970s RAM works with it, I was saying it's hard to believe anything nVidia says at this point. If you know how it works and have the time, please do tell.

    It is faster for the GPU to access it's own dedicated memory because it's not dealing with the additional latency from the PCIe bus, PCIe controller and 2 memory controllers, as well as the sheer distance. The latency introduced by the additional distance and controller chips would reduce the effective performance by more than 50%.

    I have no idea of the specifics either, but it's pretty much a given that a GPU accessing system RAM is going to be slower. We all remember the days when 'shared memory' was a commonplace feature of low end cards, eh? :)

    I got Vram stutter issues. I thought they were related to poor game programming or drivers. Now it know it's not, so I'm selling off 5x 970's and getting 3x 980's instead (one pc with single 980, the other for SLi).

    This was posted a few pages back, it explains quite a bit about it

    nice :) luckly I can live with this ram issue as I don't have any issues if and when I do I will alter my setting as needed.

    you cant fix something that is not broken .. how ever if the card was faulty I would return for none faulty one .. thing is Nvidia have aready said no it not broken its working as designed .. so I don't have no problem to worry about here. how it access its ram is how they designed it to, I was happy back when I bought the gtx970 and am still now, so all in all im still very happy lol

    Glad I didn't buy a 970. Resale value on those things must have plummeted :eek:

    it is not the same ram (gddr5 vs ddr3 or ddr4) and it is not the same duty...
    this timing doesn't mean anything for a GPU.

    it's like comparing a motorbike with a truck: both are made to use road, but with one you will be faster, and with one you can handle a lot...

    I recently put together a new system with an ASUS Strix 970 4GB and was surprised that for AAA graphics intensive games like SoM, DA:I, and Tomb Raider at maxed settings yielded a measly 5fps average faster than a single HD7950 3GB. Reducing AA from 4x to 2x, and eventually FXAA, I noticed the gap start to widen, though not by as much as I would have suspected. No issues playing Skyrim or CoD: AW at maxed out settings as the 970 easily outperformed a single HD7950 by a wider margin (that was to be expected). But really, it's all moot when you are playing 1920x1200 maxed settings and achieving greater than 90FPS, regardless of GFX.

    Anyway, my point is booerns nVidia! That last 500mb and 208bit (effective) really does hurt performance. I noticed it right away before all of this was brought to light.

    If you mean to play older games, there shouldn't be any problem. But don't count on something better than medium settings in Witcher 3, Star Citizen or other incoming high demanding games. Generally mainstream games shouldn't have to much problems, because they will have dedicated support in drivers, worse with games outside of main stream and all beta/test versions.

    Nvidia not giving out the real specs (for whatever reason) is bad, no questions asked. However, the impact this "issue" has on performance is being blown out of proportion. I game @1440 on my qnix(@110Hz) and have no issues at all with fps or stuttering. I also think one shouldn't expect smooth 4K gaming with a GTX 970, I dunno about SLI.

    Thank you. On the SLI front even the 980's in SLI start to struggle at 4K the 256bit memory bus is too narrow.

    The 380x can't come soon enough. Always nice to have more variety to choose from.
    It might even drive 980 prices lower.

    5fps increase against a single 7950? What are you smoking?
