i would choose a nvidia card too

but i don't know whether a nv card can
have hardware 2D/3D acceleration under freeBSD?
It looks like that both NV and ati does not produce driver for freeBSD.
In my case, when i install ATI9200se in my computer, i encountered the problem
that the linux kernel doen't support agp8x mode, but the mb and the video card
works togeher only in 8x mode, i cannot tune it with BIOS. It can only be solved by install
driver from ati.
if freeBSD can works fine with KT400 mb and a FX5700 card?
