NVidia SLI, which setup?

[othertomperson]

SLI doesn't increase memory usage? Take a look at Digital Storm's 4K memory usage tests. Two titan Blacks used 3.3GB at maximum. That was on Crysis 3. 

 

 

You completely missed the point. A single card isn't powerful enough to use more than 3gb of vram, the gpu itself will "bottleneck" way before the vram limit is hit. This isn't true for two GPUs. You said yourself that Crysis 3 will saturate your vram at 4k with a 3gb card, hence the 6gb versions.

A 1440p monitor, but then only go for 780 sli, or consider the 21:9 LG 34UM95 - a 3440x1440p monitor. It looks truly excellent.

Whoa that monitor is sweet! At $800 I think I'll go for the ASUS tho.

I know...but it only uses 0.3 GB more, hardly worth the extra cash for a 6GB card.

It does, I personally hope that by I look at getting a 21:9 monitor more of those 3440x1440p ones are available and prices drop. Else it'll be 2560x1080p for me

 

Hope the Asus one works out for you

It's really binary though. You either have enough, or you don't. If you have more than enough then you'll have a consistently smooth experience, other factors notwithstanding. If you don't, even if it's by a tiny amount, then you won't and tbh if you're buying a card in the price bracket of a 780 or a 780 Ti I don't see the point in settling for that.

 

I mean I've already said in another thread that I think crossfiring two 290s/290Xs makes more sense, but OP asked about Nvidia SLI so.

[Sonefiler]

Nope, even a Titan Black at 4K used 3.3GB max, and that was in Crysis 3 with the AA turned up. 

This is bullshit. Look at PaulsHardware's benchmarks of R9 290X CF, 780Ti SLI, Titan Black SLI. The 780Ti was being severely bottlenecked by many games by its 3GB VRAM.

If I were to go for 290X's which cards are the best in terms of cooling and performance?
