GIGABYTE AP64D - Radeon 8500LE - one or two ramdacs ?

and I would like to know does the ati dual display is useable in games? and which one ?

VERY few games support dual monitors.. you'll be able to play them fine on 1.. but not with two.. i'm not sure but i think one benefit is being able to use the other monitor for something else, say browsing the forums or something.. WHILE you're playing your game.. but few games if any take advantage of dual.. for now anyway i dont even know of any to list you perhaps someone else does?

Q3 and its varients I believe can do it.
UT can do multiple monitors.

Halflife can't=\ I remember looking for this when I was all into CS=)

Serious Sam can do it
