GTX 960M 2GB vs. 4GB VRAM

[Hendrik Jan van den Broek]

I've been looking into some different laptops and settled for two models. They both have a GTX 960M, one has 2GB VRAM, and the other one has 4GB of VRAM. I had already bought the 2GB version to see how it performed (it actually performed better than I expected).
I was wondering if it would be necessary for games like GTA V to send the 2GB version back and get the 4GB version instead. I've heard a lot about how the GTX 960M would be too weak of a GPU to even handle the 4GB. On the other hand I've seen some desktop 960 comparissons and the 4GB version seemed a lot more stable; there were a lot less FPS drops.
What would be the best way to go, emphasising that I play a lot of GTA V? Keep the 2GB VRAM version or get the 4GB VRAM version?

Thank you all in advance!

So if I want a 960m laptop to keep around for 3-5 years if not longer, would a 2gb or 4gb version would be better for playing future games at at least medium with 30 or more fps?

The 4Gb VRAM version will be a little more future proof than the 2Gb version. You might consider investing a little more money and going with a laptop that has a GTX 970m if you can, that will get more time out of your money, but I definitely understand having to adhere to a budget too.
