Can only confirm that the GT240 works very well, the improvement over a
9400GT was much greater than expected.
Avoid the GT210 as has very bad reviews for de-interlacing &
scaling/sharpening artefacts but this is not the same GPU as used in
GT220.

Using feature set C options has appeared to increase A/V sync offset
from close to 0ms (9400GT) to about 60-100ms. Maybe a default offset can
be configured ?
 
You could make up custom heatsink to fit your PC case.
Could use a VGA boiler tube arrangement with almost no airflow if you
have the luxury of room or to move the heatsink away from the videocard.
The GT220 TDP 58 W vs. GT 240 TDP 70W & the price difference is small.
