GPU - what is more important on calculation power: single or double precision?

a little bit of a nerdy question:

Of course this is some kind of bying advice.. but since i have a limited budget and targeting a second hand buy, i would like to know what kind of focus i should have.
As an example AMD change from the 6XXX to 7XXX a lot of .. a near 4:1 drop on double precision GFLOP power...

(the passmark benchmark is just one synthetic .. and a lot of OpenCL / GPU benchmarks scale different)

hope for an answer, greetings

Lumion is the same as a game engine (dx9).
So it doesn't use double precision or sp like if it would do a classical GPU renderer.

Just buy the fastest gaming card and it should work. ;)
