780 SLI: Two 3 GB or 6GB?

[Dtignor]

Hey guys I am doing a build with two GTX 780's in SLI. Should I get the 3 GB versions or the 6 GB versions? P. S. I am going with the EVGA ACX cooling.

You should get the 6GB version. The extra vRAM will help at higher resolutions and just a note: Watchdogs uses 4GB of vRAM at Ultra settings at 1080p.

if you got the money the 6gb version is the way to go i am assuming your not going for 1080p

It depends on the resolutions you plan on running, and the amount of money you have to throw around. In a raw capability ratio, the 6GB cards are better, but if you're looking to save a couple hundred dollars, and aren't running 4K displays and the like, the 3GB cards will more than suffice.

Depends on monitors/resolutions.
6GB will be more favorable to high resolution setups

Do you have any benchmarks proving this? I find it very hard to believe.

EDIT : Just something to add, using memory (as in buffering information) and NEEDING that information to be buffered for optimal performance, are two very different things. Keep that in mind.

In my opinion, Watch_Dogs only need 3GB of VRAM. I've only got an R9 280x [which only has 3GB of VRAM] and I play this game on Ultra. I'm getting like 40 to 55 FPS. I think this game is both CPU and GPU intensive game. But, like other people have said, if you're gonna be playing Watch_Dogs or any game for that matter on 4k? Then the 6GB is sure your card!

This guy here is using more than 5GB of vRAM on ultra settings: http://www.overclock.net/t/1491316/gn-watch-dogs-on-pc-requires-3-gb-vram-for-ultra-quality-textures/210

Looks like it was only that guy that was having that problem haha. I play this game on ultra with just 3GB of VRAM and I'm usually fine with it.

I like how its an extremely small area of his screen.
Notice how the game isnt shown, notice how none of the settings are shown, notice how the GPU usage isnt at 99-100%?
I honestly doubt that was watchdogs he was running...

Agreed... because like I said, I play this game on Ultra settings and I'm getting reasonable FPS. If I turn it down to High, I'm getting solid 60.

Get 6GB ones clearly. 3GB is pushing it, it is plenty enough for now, but there is at least one game already capable of using more than that in 2K resolution.

3GB is pretty standard now, really. And as you know, what is standard now will become weak later, so it only makes sense to have your ass covered in case VRAM heavy titles start popping out. Watch Dogs is the first of many, really.

I am pretty sure you want your SLI setup to last you 3 years or so, so prepare accordingly.

I'd go with the 6GB variant. When playing Watch_Dogs I've checked Precision X before at it's using nearly 5GB of VRAM on Ultra with AA on.
