Hi Folks, I will through the baby under the bus....
Its not the sim itself (thats my 3D math model you can do 100fps all day 
long using almost anything)
mine is on a 750mhz UltraSPARC, running UNIX, and a AMD Phenom II with 4 
cores, and a 2 graphics cards with a total of 4 screens, but you get 
crushed with the out the window crap. you just need bigger and badder 
video cards but they COST $$$$$$.
Enjoy - Have a good 4th

ps .. It also realy helps not to be running MS Sim - but ill leave that 
for another day.
