In one of my scenes, not big but with 3500 trees, flowers, bushes and 4500k Verts
the performance was 10-12fps.
That's a lot of plants, but good to know you were able to work with that many in a scene.
Time for new machine...?
Of course, always
, and at same time include an upgrade to Lumion v3
(which does work best with good PC hardware, see topic on recommended hardware specs).
More seriously though, it may be the motherboard that's now the bottleneck, older limited bus, limited speed and not in par for the new CPU's etc. The GTX670 is a good fast card (AFAIK), there's a factory clocked card that comes close to the 680 for a good comparative price.
It is strange that you did not get a better onscreen FPS for the GTX670 though. I wonder if you might have the Setting --> Limit Low Memory turned on? If yes, turn it off as with 4GB you will be fine, then close Lumion and re-start it.
