Any other advantages to extra VRAM besides better performance for higher res?

In the process up upgrading the GPU to get ready for when I get my 2560x1440 monitor. Just wondering if there's any other advantages to having more VRAM than just better performance at higher resolutions?

That's it. Maybe games in the future will require more. Its just like regular ram where having more doesn't mean jack unless it's needed.

it makes it harder to crash from maxing out your vram.

heavily modded Skyrim floats around 2.6-2.9gb of usage for me, but every once in a while it hits 3072 (I have a 780) and it either locks up or CTDs.

Even at higher resolutions, over 2GB doesn't really make a significant difference, if any at all.
Mostly, extra Vram is just "future proofing". Some game may come out with some very, very high resolution textures or very poor memory management, and need 2049mb of video memory, and throw a hissy fit and stutter all over the place because you only have 2048mb. Some games also don't let you select higher settings without "enough memory", not because they actually need it for those settings, but to promote higher end graphics cards with more memory.(see: max payne 3)

Got ya. My next question would be would it make more since to SLI 4GB 770's or just get one 780 TI? I was going to SLI two regular 780's, but it might be out of my price range.

I'd go 780Ti personally. Single GPU is just a cleaner experience.
Two 770s will perform better in non-CPU bound games where SLI drivers are good.

Well sli 770's blow away a 780 on its own so really it depends on if you will be willing to buy another 780 later. I wouldn't count on a price drop as the higher end cards don't usually see big drops even second hand.

I'm going 770's but only 2gb but I'm also sticking to 1080p and mostly doing it for 120hz 3d gaming. I'd go 4gb 770's personally, but only because I think the 770 is the best bang for buck at the high end spectrum.

Edit: Misread 780 ti as just a normal 780. Even still, 770's will do better for about the same price in the majority of titles, I would think. That said, I was torn myself on that decision and decided to give sli another chance after a 5 year hiatus. Both are good options but a 780ti single card will be the cleanest option. Sli can and will be messier at times.

Well, I have a 680 already so a 770 would be a small upgrade especially if I only went with the 2GB versions. I did have a smooth experience in SLI when I tried it out a year ago with my 680. I might just do the 780TI though. That way in a few months if I want to SLI another, I have the choice.

770 is only slightly more powerful than a 680.

You'd probably be better off asking this on a technical forum, but from my (very) limited understanding of video RAM, it's not just used to store the screen display, but if there is enough space then it's also used to store the textures and also shadow screens. Textures are stored normally in video ram, and also (if there's enough video RAM, and the game supports the process) pre-shrunk and pre-enlarged, to save having to resize them in real time during the game, and various copies of the screen (known as shadow screens) can be used so that the game/hardware can draw/alter one screen, whilst a different screen is sent to your monitor, thereby avoiding screen tearing or partially drawn items appearing on-screen.

Then again, the techniques I'm describing are years old (we're talking Voodoo 2 and maybe even Voodoo 1) so it's possible that modern GFX cards don't need any of them as they have other ways of doing things, or are just so fast that resizing a texture is just as quick as reading from a pre-re-sized texture, I don't know.
