Yes, if your graphics card can run at TV hsync and vsync rates, and
output composite sync.  If it supports the video modes but won't
output composite sync then you need a sync combiner, I'm using the
design from
http://www.nexusuk.org/projects/vga2scart/
with an nVidia 6150 integrated GPU.  Easiest way to build it is to
chop the end off a VGA extension lead, solder a scart connector on the
end then build the sync combiner into the scart connector.  My TV also
needed 3V on the fast blanking input (pin 16) to make it use RGB, some
TVs you can switch manually.
