just what is "intensity"?

Did you see this?

--intensity|-I Intensity of GPU scanning (d or -10 -> 10, default: d to maintain desktop interactivity)

and what does that mean? how does it affect miner output?

GPU-README (yeah another of the files people don't read)

INTENSITY INFORMATION:

Intensity correlates with the size of work being submitted at any one time to
a GPU. The higher the number the larger the size of work. Generally speaking
finding an optimal value rather than the highest value is the correct approach
as hash rate rises up to a point with higher intensities but above that, the
device may be very slow to return responses, or produce errors.

NOTE: Running BTC intensities above 9 with current hardware is likely to only
diminish return performance even if the hash rate might appear better. A good
starting baseline intensity to try on dedicated miners is 9. 11 is the upper
limit for intensity while BTC mining, if the GPU_USE_SYNC_OBJECTS variable
is set (see FAQ). The upper limit for sha256 mining is 14 and 20 for scrypt.

well, the intensity was set a -1 on the little machine that i am playing with. moving it to 5 raised the hash rate from 6Mhash to 10Mhash. moving it to 6 looked like it caused the rate to drop a little, so 5 it is.

What hardware are you using for mining?

I'm using an Asus C60M1-I AMD C-60/ AMD FCH A50M/ DDR3/ SATA3/ A&V&GbE/ Mini ITX Motherboard & CPU Combo

The goals for this little miner were low cost an low power. as it sits it cost $180 dollars and is using about 40 watts. i'm going to be adding a sapphire 6570 video card tomorrow. that will bring the cost up to about $240.
