Hello All,So I have a Q9550 overclocked to 3.7, 4gigs ram and a GTX260 card on win64. After seeing the reviews decided to get a GTX570. After following the driver removal instructions on Nvidia's web site I removed the drivers swapped cards and installed the new drivers.With the GTX570 installed the benchmarks showed double the power of the older GTX260. So eager to see what FSX could do now I loaded it up. And if I had not put the card in my self I would not have believed it was changed. Really not (1) FPS more, and not the least bit smoother. How is it possible that the card could show such improvements in 3 different benchmarks but absolutely nothing for FSX? Has anyone else experienced this when changing there card. When I went from a GTS8800 to a GTX260 I noticed a big increase in smoothness, not a big FPS increase but smoother.I just don't see the difference here I was expecting from other reviewers.Regards,Ken ----Sorry this is a duplicate post please delete---
