FSX is CPU limited to be sure. But, an antiquated graphics card will be a huge disadvantage if the OP wants to take advantage of high res (particularly on a large monitor). For the longest time, I flew at 1600x1200 on a 21in. With my GTX580, I'm now running at 2560x1600 on a 30 in monior. I could never go back.

Also my 5970 allows me to play FSX @ 1920*1080 on a 27" at 60 Hz but I meant that he has to expect no big improvements on FPS because a $1000 brand new GPU in FSX works pretty much the same than a $200 one.Of course he has to aim for the best within his budget and old cards drop the FPS sure.Then you are a lawyer, so I have to pay lot of attention to what I say before seeing you in a court -

Only get the 570 or 580 if you play other games that can use the extra power. FSX is a CPU limited engine and there's virtually no difference between any of the GF110-based cards in it. (460, 560 Ti, 570, 580)

I found out that recently myself, I have a GTX 460, and can't see much difference in framereates,but the GTX580 is a bit smoother.I don't use the PC for other apps apart from FS9 and FSX

I'm no expert, but from what i have read in the various forums, there are really good graphics cards for FSX and then there is Overkill.

Thanks again guys,As I mentioned earlier, I am on a limited budget and have to use that extra that would cost for the GTX580 ( $150 more) on replacing my rudder pedals that are U/S at the moment.If my rudder pedals didn't need replacing then I would simply go for the GTX580 straight up as I also play MW3 and BF3 and they are just a FPS hungry as FSX.So I thank you for all your comments / advice and may stick to getting the Gigabyte GTX570 Super Overclocked for $409.I only run on two 22 inch Monitor's at 1680x1050 @32bit so I hope the 570 will preform enough to my satisfaction.I went from the GTX295 down to my current 9800GTX (GTX295 died) which makes FSX in default a bit of a slide show so I am hoping marvelous results from the new card ... lolThanks againAdam
