Titan X or 980 Ti [12GB vs 6GB(?)]

Hi, I was just about the purchase the Titan X and then it dawned on me.. I really do not like the idea of a my GPU Boost 2.0 card throttling because of temperature. I understand the Titan X is rated up to 91c, but 86c just feels like it's cutting it too close for me.

To my questions, though..

I run an ITX setup with a single GPU and single 1440p monitor. I have no plans at all to upgrade to 4K.

The rumors are saying the 980Ti (or whatever they end up calling it) will come with a fully unlocked GM200 just like the Titan X, but have only 6GB.

Is 6GB of memory enough for a single 1440p monitor? I prefer to max out all settings including AA, if that helps to better determine.

I did read someone saying they managed to get Shadow of Mordor to use up 6.5GBs on a 1440p resolution with their Titan X. Just doesn't seem possible..

Anyways.. some clear direction would be greatly appreciated.

Its all ways nice to have the extra memory there with the titan, but with no plans to upgrade and only another year before the next titan.
the 980 Ti seems like a much better option, not to mention that board partners will bring out 8,10 and even 12GB versions of that card.

Get the 980 Ti. Yea.
I'm not a computer genus or anything but I've seen a couple tests of graphic intensive games at 4k and they usually use around 5gb. So maxed out games at 1440p would probably use a little less

I just read that post on LTT and it doesn't seem true, I'm no expert and I probably am wrong and hopefully someone will explain why 😛 But my take on it is that to enable VRAM stacking with DirectX 12, a game developer needs to enable split frame rendering, where each video card renders half of the screen... the video cards aren't going to communicate with eachother as much as they do now with a typical Crossfire/SLi config, they'll need to communicate to an extent so you don't get one half of the screen at a higher framerate.

Over the last couple years I have read and heard quite a bit about DX12 and what improvements and new features it may be bringing. Two I am really interested in are the cross manufacturer compatibility, AMD & Nvidia working in tandem, and the VRAM stacking option.

Has anyone running multiple cards in Windows 10 RTM experienced either of the these two "phenomena"?

There isn't a game support DirectX 12 yet.

VRAM stacking is meant to be implemented with DX12. AMD has already done it with the Mantle API, so it's pretty much a shoe-in for AMD cards at least. Cross-manufacturer support will be supported, but will not experience scaling of matched cards, no doubt.

DX12 is already implemented in Windows 10. Hence why I ask if anyone is experiencing the stacking or cross GPU results. Not asking if you also believe it will implemented, but if you are experiencing it.

I haven't ever seen a report of a Mantle supported game allowing VRAM stacking by turning on Mantle in game settings. And all the arguments about GPUs and explanations about VRAM mirroring I have never read anyone claiming while using a Mantle supported game that their VRAM was "stacked".

that should have nothing to do with how the system's API reads your GPU(s). even if what you said was relevant, 3DMark's API tests should show your memory stacked.
but even in Windows 10, using the correct GPU drivers, VRAM should still show as stacked or mirrored and the cross manufacturer cards should both still show in system information instead of just the one you've chosen through BIOS. if it is being implemented yet.

no programs or games have been written to take advantage of these features you speak of in dx12. stacking WILL NOT occur unless the game has been written that way!!! listen to what I'm saying here OK, none of the older games/software will allow stacking of your cards vram, by old I mean gta 5, witcher 3 etc. the only way they would allow stacking is if the developers were to rewrite these games to stack vram. now look at this logically, THAT IS NOT going to happen OK. however developers will no doubt release programs and games in the future to allow these features in dx12, but that's solely dependant on the developers, NOT THE CARDS. also, to take advantage of all the features of dx12 you will need a nvidia 900 series card. anyone saying anything different to this are stupid or talking bull.


 
I have the titan and its a better card no matter what they say more cores, memory, and set for future upgrades the ti is a poor mans titan. Its a fine card but I like you would rather be set for the furure. My titan x overclocked would run circles around there ti's if they would admit it or not. scores mean shit when the one scoring the product is the one on a budget
