Thanks art,computer i am using mitac dual core 1.8Ghz cpu 2gb mem vista 32bit.Yeah the problem i have is not enough money at the moment. I have gotten good performance with the 7300gs nvidia, would the 8400gs be not as good as the 7300gs? Would it lower the Fps? I always run fsx at the lowest settings, it may not be the idea for some, but I value the smooth frame rate over the details in the game.I know the 8600GT or 8800GT would be the ultimate, but not sure I would be able to afford it here in OZ!Thanks for your help art,kind regardsNathan
