I love my Matrox G450. It's stupidly old and has few features - I
don't know if it can do much 3D or not, but I don't really care. It's
got two vga outs, it's passively cooled, and it doesn't seem to get in
the way. I run it in a computer in a garage that I'm just now getting
around to insulating - over the past summer ambient temperature was
often in the mid 90's F, sometimes higher, and the computer ran 24/7
with no troubles.
