The GTX 770 only has a 256bit bus, meaning that it cannot fully use the 4GB, but it still performs better than 2GB

neither card can fully utilize 4GB of VRAM, getting a 4GB version would be pointless.

Get the GTX 770 2GB , The 4GB is a little useless and the 760 4GB is just outragiously pointless....

you could use the high texture packs for skyrim :P they require more than 2GB vram

In *theory* more video memory means better performance at higher resolutions. Multi-monitor gaming and all that. 

 

But if you're just pushing a single monitor at 1080p, the extra memory is pretty much wasted. And that's ignoring the fact that, like others have said, 760 and 770 wouldn't be able to make full use of it anyway.

then why do 760/770 4 gb cards exist?

 

Because people do things other then gaming at 1440p and up :). Add to that, people actually believe 4k gaming is possible, due to laughable articles by "tech people", so suckers will buy them.

 

4k gaming on games with decent graphics IS possible...with an extreme chip and a 250 dollar motherboard...and 4 top of the line GTX's. You can pull a whopping 43 fps with 4 titans at 4k in BF4. I don't even want to think about the power draw of this setup, let alone the cost of the setup itself.

It isn't so much the cards can't utilize it at all, it is the bus size restricts the amount they can utilize of it. It is possible to push a card to its absolute limits through texture downsampling and other elaborate ways but for 99% of users saying it is pointless covers what they need to know. Those who intend to utilize more will also more likely have a larger gpu budget simply because the panels they will be using to actually see the results of the extra work cost so much more.

I guess to summarise, for the informed consumer it is pointless however a large amount of consumers aren't informed or worse ill advised and like big numbers. However if they can increase their profit margins by a few percent per card by slapping some extra vram on it and selling to the ill advised then you can bet your bottom dollar they will. At the end of the day nvidia and amd alike are companies where profits are important.

More options?

The extra vram can be used in some cases of rendering.

Extra RAM could be useful in SLI, as with SLI you double GPU power but stay with exact amount of RAM, so single 2gb card or SLI 2x 4gb cards.

SLI or Crossfire DOES NOT exactly double your performance.

Each program / game scales differently. You could be getting a 0% gain, a 50% gain...or 80% gain.

With that said, from all the reviews and tests conducted thus far on the later generation of graphics cards (i.e. GTX 600 and 700 series, HD 7000 and R200 series), most games can get a performance increase of 80%-90% when a second card is added

I am jelly. :) 50fps at 4k. Dayyyyyyyum. He should put that bad boy on youtube or contact Linus with his build. Would love to see it.

You should go by this rule of thumb: for every 128bit's in the bus it can utilize 1 gig of VRAM so for a 770 that would only be 2 gigs
