OK, let the "mine is bigger than yours" game begin. ;)
here is my machine, dual intel xeon X5560 (2.8GHz),
quadro FX 5800, about one year old. running fedora 12
with nvidia driver 260.19.12, screen size 3840x1200
(using twinview, in case that makes a difference).

I get :
1AY1 : 209 fps
1IGT : 55 fps

here is the vmd startup message.
