yes, of course there are 2 diff versions because those gc hav 2 diff gpu geforce3 vs geforce
i think to light you, i hav to explain diff between agp & agp pro slot
the pro type will give just superior power for gc will need it (like for geForce3 gpu will needed good power alimentation)
but a geforce gc need less power & i think it exist in agp version, not agp pro
a geForce gc is an old gpu version
if you want to buy a gc with a "minus" gpu that geforce3,
search hawk Geforce2 gpu gc
there is a lot of brand with this gpu & for any budget
I would like to Invest for my PC !!
ok, buy nothing.
