Hi Kenneth:

For your desktop did you ever compare with straight VGA for the same
monitor? Obviously the conversion from D to A in the video chip then back
from A to D in the monitor must take some toll with VGA.  However it is
possible that toll is not really detectable by human eyes so I would
appreciate comments on that aspect from you or anyone here who was curious
enough to do such comparisons for exactly the same monitor/hardware/software

Thanks for the above information and also the other information on ADD2
support within the X intel stack and alternative places to buy ADD2 cards.
Those alternatives would involve border hassles/fees (I live in Canada) with
an exchange rate that effectively increases the cost of the US alternatives
when converted to Canadian dollars (the NCIX cost for both ADD2 and video
cards I quoted was in Canadian dollars) so it still appears the ADD2 cost
doesn't compare well against low-end ATI video card alternatives.
