Hello Lads..
I was thinking about having my current 3 year old PC upgraded but it may be easier & cheaper just to get another built, how would FS9 run with something like this:
Something like: AMD 64 X 2-6000
3gb memory
300gb hard drive
GeForce 8800 GT
:-?
Your FS 2004 will run fantastically on a system with that specification... 8-)...!
Remember, we are talking about FS 2004...NOT FSX!.. (which is a completely different kettle of Fish)...!!
FS 2004 will run on most of today's, and most of yesterdays, computer specs...

...!
Paul...Have Fun with FS9!... 8-)...!
