Gigabyte GeForce GTX 1060 3GB or 6GB?

Solution
Wont make a colossal difference, but the 6gb version is currently the king of 1080p.
Depends on your budget though. If I am on a tight budget, I wont miss the extra 3gb of VRAM, but its presence will definitely increase the longevity of the build in terms of future game scaling and optimization. Also varies from game to game. Scroll down and compare some of the FPS deltas to get a more broader picture... http://gpu.userbenchmark.com/Compare/Nvidia-GTX-1060-6GB-vs-Nvidia-GTX-1060-3GB/3639vs3646

along with the 120+ extra cuda cores too! The 1060 6gb is the smart buy. The 3g version is on a budget. Agreed with all the rest of the points about the 6gb version.
 


Agreed, it's annoying. However the cuda core count of 1152 vs 1280 (correct me if i'm wrong) is so little in my opinion that performance is pretty much the same between the two GPUs if we take VRAM out of the equation.
 


I have mentioned clearly, that if budget permits, the 6gb is a better buy. But you have to consider the OP's budget restraints as well, which he has specified.
 
1. The 3GB version is 7% slower than the 6 GB version and this has nothing to do with VRAM, it's because the 3 Gb version has 10% less shaders.

2. You have to weigh that 7% difference against the increase in cost. In some cases, due to supply and demand the two are almost he same price depending on model.

3. **VRAM has show no impact on card performance** at 1080P or 1440p ... at least not in TPUs game test suite. If ya want to see that data look at the techpowerup testing for the 3GB and 6 GB MSI cards. Few would attempt to argue that 3 GB is inadequate at 1080p (some will but if they are correct 11 GB is inadequate for 4k at 4 x the resolution) . But logic dictates that id VRAM were an issue, it stands to reason that we would see significant widening of the performance gap between 1080p up to 1440p ... but that doesn't happen as gap doesn't change

1080p = 6%

1440p = 6%

Only at 4k do we see a noteworthy jump (+8%) and its far less than would be expected.
 


yeah, its minimal, i was more referring to the cut down nature of the GPU than the performance. But i'd agree completely agree with you.
 


absolutley
 
Nvidia should have labeled the 1060 6GB as the 1060 Ti and left the 3GB the "regular" 1060 to prevent consumer confusion thinking it's ONLY just 3GB vs. 6GB (which is what Nvidia is well known for). They've done this with previous x60 series with cut down shaders differentiating the two. But there is a wider gap difference in more DX12 game benchmarks since the GPUs were released last year possibly hinting at which GPU will have more longevity. In DX11 the gap is still close. Case in point in DX12:

I just have a feeling going into next year and beyond, a lot of people who chose to save money over the 6GB may have buyer's remorse for not just saving/sacrificing to go ahead and get the better GPU up front. Even at 1080p and like all throughout history, there is only one way game VRAM demand goes over time: up.
