tl;dr, sli keeps total vram the same, approximately, for a common game's perspective, compared to a single card.


this is mainly related to the fact pci-e is extremely slow compared even to the slowest vram around so we need vram on the card, not bouncing around cards through pci-e.

Well atleast with EVGA you could have had the chance (unfortunately your chance ran out just before it would have come to good use), havent heard of other companies having a "step-up" program

How about a game that can have 200 vs 200 vs 200 players in the same area?
With plenty of magical-colorific graphics going off constantly.
Fighting and existing with up to half them on the screen at any given time.

Would/could it make a difference then?

Hmm, video ram was always the key component in any large player amount mmos that get laggy because of the pure #s before. (As well as system ram).

Take Dalaran, at the bank, on a High pop wow server as a prime example. It was perhaps the single best way to counter the loss of frame rate experienced by everyone.

I do think there could be a cap/diminishing returns scenario at a certain point and maybe we have reached it. But it would go against everything I have ever witnessed since '97.

WoW is largely CPU-limited in such circumstances.

wow has never passed 2gb of vram used for me at 2560x1440 on one of my titans or 780ti, i dont think youll ever need 6gb for that if thats what you play. full population server in org.

Lots of Vram is for 1440 - 4k resolutions and guys who run multiple screens. Also for people who like AA and let's be honest, who doesn't? Titanfall uses 3gb+ vram maxed out @ 1440p on my classified 780s. 4gb is the absolute minimum I would buy now.

There is a lot of misconception with using and caching VRAM. 3GB is plenty for 1440P and Titanfall is no exception. People tend to look at their monitoring software and say "Look, it's using all my VRAM!"

Dependant on the game, it will cache what is needed and throw what isn't out as when the game requires it. If the game is buffering the next 10 frames at 1440P on a Titan it will store 3-4GB say in Titanfall. Where as on the Ti it just won't cache as much, and also a lot of data that isn't required on screen any more will be discarded quicker, but the buffer will appear more full.

It's not an accurate representation. I can max out 4XMSAA and insane textures on my Ti at 1440P in Titanfall, the game that apparently has "Insane VRAM requirements". Until such a time a game gets excessive stuttering, and eventually grinds to a hault, your VRAM is doing a perfectly acceptable job.

Yes, except for the fact that once afterburner OSD starts approaching 3100 MB the entire game will artifact and crash (insane textures). Change the textures to very high so vram doesn't go past 2700 MB and the problem is eliminated. So how is it your 780 TI doesn't do this but my 780 classified does and they both have the same amount of vram?
