Um doesn't your GTX 780 share enough system RAM already?

If you've only got 8GB of system RAM maybe you should go to 16GB or 24GB but even with 8GB it should have shared 4GB of that to your GPU allowing it to have 7GB total with 3GB onboard + 4GB shared = 7GB video RAM.

A graphics card isn't necessarily all about the vram. That really depends on what resolution you're running things at. Just because the r9 290 has more vram doesn't mean it will always perform better. Generally they are about the same, trading for 1gb more vram wouldn't make that much of a difference.

I think nvidia might be planning some kind of unified vram/system ram in 2016 with the pascal architecture. Though under the impression while reduced it is still going to be a bottleneck.

I personally think 8GB is fine.

System ram allocated to the gpu is useful for storing textures etc, and is immensely superior to a hdd page file. But there is no getting around the system bus bottleneck, and the time to retrieve the data. So while extremely useful, there is no getting around having adequate vram, if you want smooth gameplay. I think 3GB vram is ok for now.
