5760x1080, 3gb vram enough?

Hi

Specs:
EVGA GTX 780ti ACX cooler (1250Mhz) GPU
Intel core i7 - 4770k (4.1Ghz) CPU
ASrock z87 Extreme6 MOTHERBAORD
Seasonic 1000w 80+ Platinum
DDR3 4 x 4GB (16 GB) DDR3 1600Mhz RAM
2TB HDD
256GB SSD
Thermaltake A31 CASE
Corsair H100i CPU COOLER
5 x Corsair SP120 Quiet Edition CASE FANS


I have a choice of either:
Buying another 780ti with 3GB ram
or
Selling that and getting 2x 780 6GB ram

Which would benefit me the most?
Im wanting to play all games at ultra with low AA (FXAA).


I have about 3 games out of 70 that show over 3000mb vram usage

in terms of games i play and future games, would i see more fps on 2 780s (6GB) or 2 780 ti's (3gb) at 5760x1080

Thanks, very worried of spending about £500 if i have vram issues

  1. if your planning on staying 1080p than 3gb should be fine, but you can also be somewhat future proof by getting the 6gb vram when 1440p comes to mainstream. my personal opinion is that the gtx 780ti is going to be outdated by the time 1440p is going to become main stream.

    I have two 7970s (also 3GB of Vram) and it shouldn't be an issue. I also am running 5760x1080 and I can play everything on ultra (even crysis 3, but with lower AA settings). It's never just about RAM, but also the actual compute performance of a GPU, in which case the 780Tis will blow the 780s out of the water. And games that take that much Vram are unoptimised...
    I wouldn't sell a 780Ti to get lower end cards with more ram.
  3. I would say 2 780tis will always perform faster then 2 780s, regardless if how much vram the 780 has.

    Ofcourse, the ideal situation is getting 780ti with more then 3gb vram LOL
  4. I would recommend the 6GB Version if you are planning on going 4K. It almost as good as the beastly r9 295x2 http://hexus.net/tech/reviews/graphics/69713-palit-geforce-gtx-780-jetstream-6gb-sli/?page=4.
  5. I think the amount of need for vram is overstated.
    Here is a series of tests for 2gb vs. 4gb.
    Look particularly at the 5760x1080
    cases:

    I think you would do better with 3gb and GTXt80ti.
  6. I'm feeling the two 780 Ti's as the speed is more important than the overkill on the VRAM. Bottom line is multi-monitors generally need more juice than a single card can provide.

    A lot of good info in this review of the Asus GTX 780 6GB Strix:

    Quote:
    "Overall, this makes the card roughly 12% faster than the reference design GTX 780 with 3 GB. But hold your horses as this increase is only achieved by the overclock out of the box. The extra memory really doesn't do anything in all but one game, Watch_Dogs, and that at only one resolution, 4K. All other games at all other resolutions, including 4K, don't show a noticeable performance improvement. There is also no way for a current GPU to drive a 4K monitor at playable framerates by itself, no matter how much memory it has. There is simply not enough shading power. The additional memory doesn't even make enough of a difference in SLI to make up for the cost."

    This is with No AA. You have to assume that adding AA would tilt more in favor of the 6GB 780.
