You are one 6600 GT & 512 Meg of more Ram away from flightsim nirvana. I'm running a A64 3200 with the above hardware and it's smooth as Butter. \:\) Only stuttering I get is when I accidently fly though a recently torn in half ground vehicle with THE GUN at my disposal. ;\) Trick is to stay above the shrapnel to avoid this effect. I run out of the box settings with Vehicle traffic checked @ 1024X768. no aa no af.
