hey fellas, so I'm planning on buying a the Gigabyte GTX 770 Windforce OC 2, but I'm not sure which version to get, 2 or 4gb of vram.
I know that vram isn't the most important part of a video card, but I'm planning on getting another one for SLI in a month or two. This would be accompanying either a 3x1080p, or a 1440p setup, so keep that in mind. I will be gaming on them, (battlefield 3, and 4 when it comes out, crysis 3, and the new wave of games to be released alongside next gen consoles.)
Opinions?
I feel like it's better to buy the 4gb version, as I'm afraid that 2gb of vram could bottlekneck my GPUs when in SLI.
any and all opinions are welcome!

Id get 2GB for 1920 x 1080 / and 4Gb if more resolution .... for 5760 x 1080, definitely the 4GB

For triple displays, 4GB for sure. As a side note, extensive tests were made on the GTX 670 and they determined you needed three of them in SLI before the memory beyond 2GB was worth using. Well, 3X670 is about equal to 2X770 so you are in luck. 4GB it is.

I'll buy GIGABYTE GeForce GTX 770 windforce 3x 4GB and I saw reviews saying that it blows air back into case. I will have Corsair 500R case,so how should I manage fans/airflow, IF this with air blowing is even true ?

Most aftermarket GPU coolers DO blow into the case. The "stock" or "reference" cooler draws air into a shroud and blows it out the back of the PC (where the video cable attaches). I normally have fans in the front bays of the case to pull in cold air. Then fans in the back to blow the hot air OUT of the case.

You shouldn't have cooling issues with the Corsair 500R. The side fan on it should bring in plenty of cool air to help cool things as well. Just make sure there's 11" of space for the Gigabyte Windforce card as it is long.

Yes I can install 4xy mm whitout drive cage and 3xy mm with drive cage so with place there should be no problems. A little off topic,what if I later buy EVGA GTX 770 4GB and do SLI will SLI work fine ?

Yes you CAN SLI any GTX 770's together. Even if they are not the same amount of memory. However, the smallest card will win out. So if one is 2GB and one is 4GB they in a pair will act like they have 2GB. Also, if one card has a slower clock speed they will both run at that slower speed.

But isn't it risky going with the 2gb version?
Next gen consoles have a lot of VRAM to play around with and 2gb is already looking like the bare minimum at the present.
These next gen games could eat a lot of VRAM.

1 Screen - 2GB
3 Screens - 4GB

If you're planning to run 3 monitors as you suggested before then get 4GB. My point was you can SLI any GTX 770 with another. However, if their specs don't match (be it RAM, clock speeds, whatever) the lesser card wins out.

So if you get a 4GB card now and buy a second later that card also needs to be 4GB in order to take advantage of the 4GB of RAM in SLI.

I've got the Gigabyte GTX 770 Windforce OC 4GB and I'm gaming on 3x 1080p screens + got an auxiliary (i.e. 4 screens in total). The GPU would have struggled hard if I got the 2GB version. So, get the 4GB.

However, you then say...

... you'd be bottlenecking if you had 3 screens and had 2GB version. Having 2x770 2GB wouldn't bottleneck unless you had Ultra settings but even then, double the processors would be fine. In fact, 2x 770 2GB has higher benchmark than a Titan!

IMHO, if you got the money, get a 780. It performs very similarly to the Titan but without as heavy of a price tag. If you really feel you need it, buy another one later.

+1 very true! You won't be disappointed with the 4GB version. I have 3 screens (5760x1080) and 2 of these in a SLI setup. A HEAVILY modded Skyrim in 3D surround still gets 37 fps average and 54 fps in 2D mode. Vanilla Skyrim gets 60+ fps even in 3D. I use more than 2GB of VRAM for this, so get the 4GB version.
