Im just interested about those FS2004 clouds. What kind of performance do you estimate i will get with a P4 1.6 Ghz, 512 Mb RDRAM, Leadtek Geforce 2 TI 64 MB, Windows XP Home. I know also that i need to upgrade my video card. There seems to be alot of controversy on the subject but can someone give me a solid recommendation? Im considering a Geforce 4 Ti 4800 128 Mb but if there is something better, please let me know.
