Based on what you said, I think 290x 8GB will be able to last very long.
The reason people upgrading most probably due to RAM issue.
Let's say
HD7870 2GB only use 40% but 2GB RAM.
But if HD7870 have 4GB, you might not even need to upgrade now.
So let's say 290X 4GB. Probably some stuttering in newer games because low VRAM.
With 290X 8GB no more stuttering.

In another word:-
290X 4GB
390X 4GB
Running game XXX that need 6GB VRAM.
390X 4GB - 60fps
290X 4GB - 10fps
Reason:- 390X is faster to process so with same RAM, it can generate faster image to keep dumping out and no need to store so long in VRAM.
But 290X is slower than 390X. So it work slowing to store into ram and dump to HDMI.
But...if we use
290X 8GB - 35fps
Why I predict 35fps? Because it has more RAM to store and put out to HDMI.
We all know that once VRAM got full, your FPS will tanked.

Summary:-
R9 290X 8GB will be future proof.
This is what I found, just rerun the test to get the screenshot. Leftmost picture are High setting while next to it are in ultra setting.
Two settings tried, namely High and ultra setting. both utilises similar amount of GPU which are 30-33% and VRAM was maxed out by using 1.9GB out of 2GB. But I found that ultra setting uses 1.5GB of system memory, i guess this is the sign of bottleneck, while High settings wew use only about 500MB System memory.
My experience: High: very playable altho FPS are not that great.
Ultra: stuttering like hell...
Detail :
Ultra setting: everything max out with AA set to MSAA 8x
High setting: everything set to high with AA set to FXAA.
