3gb of Vram enough? - Page 2

post #11 of 46
Thank you for responding, and please do not mind my noob questions.

I spend a lot of time daily reading what you guys write\discuss here, and learning a lot.

I really appreciate your response.

One more question if you guys dont mind.

So, in my case, getting 6GB card would be waste of money, where, i would (so far) never be able to use that much memory with current monitor\setup and current games?

Thanks again! thumb.gif

I see, thank you very much!

so, in future, if i decide to go SLI, i will be having 6GB of memory anyway and dual gpu?

Thanks thumb.gif

When you get another GPU the VRAM doesn't add up, unless you are using programs with dedicated memory allocation algorithms (not games).

 

So 3GB + 3GB = 3GB :)

oh ok, well i am completely confused now.

i will have to read more about sli and crossfire, probably that works in similar way.

I will let you know my findings! (of course i am joking, u guys know it lol - thumb.gif )

No 2 3GB cards is still 3Gb, it mirrors between them.

Contrary to what I have heard and read countless times (probably 9/10 were just people parroting back something they'd heard), I have found that I get equivalent performance at all identical settings on my 1440p displays, running FXAA, compared to the 1080p running 4x MSAA or higher, and the 1440p looks SIGNIFICANTLY BETTER. I have tested this with both my SLI 680 Lightning's (2GB, Aquacomputer AquagraFX FC blocks, at 1493core/7844mem) as well as my SLI 780Ti Classifieds (H2O, 3GB, 1312core/8108mem). CPU is 3930K@5Ghz and 16GB (4x4) 2133c9 @ 2540 9-12-11-26 1T.

I don't have a chart or anything, it was just something I did for my own curiosity, but the performance difference never exceeded 9pct and was usually within a few frames.
And, most importantly, even the Lightning's with "just" 2GB VRAM NEVER ONCE ran low on memory.

My (I believe to be informed) opinion is that the whole "OMG I need a billionz VRAM's or I will fail everything" trend is not reallyjustified.

Sure, if yyou are looking for 1440p with 8x MSAA then the more the merrier, but I also think that it's ridiculous, and that the difference is SO INCREDIBLY SMALL, that people claim to see a "big difference" with anythingmmore than a low-moderate amount of AA at this res or higher.

^This.
I run 1440p with a Titan. I don't get to use more than 3GB of VRam in anything but GPGPU progressive renderings.
Not games, not extremely high-poly 3DS/Maya scenes (far greater texture sizes than any game, far more polygons than any game) care about more than 1.5~2.5GB of RAM, and that's what is allocated on the card (what ppl see reported in GPU-Z), not the amount that would actually penalize performance by bottlenecking PCIe 3.0 16x .

Think of it as a girlfriend / wife with 6 linear feet (2m) of closet space: they could easily spread their stuff and make a 12ft closet look full by your standards.
But till "yesterday", 6ft were enough. Getting 12ft of storage is part of the circle for asking for more clothes etc. Part of the consumerism plan =/= real needs.

The fact that 2.5GB of VRam gets pre-allocated in a GPU, doesn't make it a fact that a 2GB or even a 1.5GB card would bottleneck, and completely irrelevant to the fact that you can make some titles bottleneck your card using ridiculous settings.

Step one is to realize that it is a fact that some settings are ridiculous and have no value in being selected.
Yes, some games literally "troll" you with ridiculous settings, that bring even the best cards on their knees.

I like - like everyone - my games to look as good as possible, but that doesn't mean that it is "maximum settings or go home".
I like to enjoy my games more than bragging about using maximum settings, plus my 1440p looks better with less than maximum settings than many "ultra-or-go-home" bragger's with 1080p panels.

What is the point of getting 6GB card then? at least for another year or two? As i understand, 780ti 6GB will be much more expensive compared to 3GB one?

Thanks

Pretty much everyone who uses more then 1 monitor for games with AA enabled need more then 3GB

i see ... i though people use sli\crossfire because of that, but, since memory stays (3gb = 3gb (2cards)) as a single card, i am still confused.

Time to do some heavy reading smile.gif
