I had AMD 64 3200+ , 1 GB PC3200 RAM, NVIDIA 6600GT 256M DDR3I have now replaced the videocard with a NVIDIA 7950GT 512M andupgraded the RAM to 2 Gb.My result in FS9 is that fps overall seems to be somewhat higher but the frames are not of better quality which has been suggested wouls be the case. But as before the fps vary very much. Stutters might be somewhat less pronounced but still exist. I must say I had expected better result.Overclocking my CPU (first 2.2 GHz then 2.4 GHz) yielded maybe a slight improvement. Therefore is it any point to also upgrade the CPU? If so there are now att tradera (eBay) a FX-55 and a AMD 64 X2 4400+ out for sale. How much more could they give compared to instead OC what I already have?

For what it's worth, my second system is a 2ghz core duo, 7950gt 256mhz PCIe, 800 fsb, 2ghz ram. In FS9 I get 50-60 fps at KLAX, everything on and maxed. NO add ons, though.Bob
