hi all,as we all know, nvidia has always been the card for flightsim, whether being fs9 or fsx. A while back I decided to upgrade my nvidia gtx 9800 and made the switch to ATI(now AMD) for a change. I now have the radeon HD 6950 2GB which has been sufficient for my gaming whenever i have time to sit down and play. Now, recently i decided to start simming again and am reading everywhere that nvidia still is the undisputed queen of cards for fs. If i were to switch back again, what would be the equal or better nvidia counter part for my current 6950? my current setup is as follows: gigabyte ep45 ud3r mobo with a Q9550 @ 3.6ghz, gskill 8gb ddr2 800mhz 5 5 5 15 2T, 120gb SSD(OS+fsx+dcsA10+battlefield3+random apps), SB xfi sound card, corsair hx620 psu, 2x320gbRAID0, 1.5TB WD, 2x23.6" Asus LCDs at 1920x1080. I only run the games in one screen so this goes for fsx which i run in windowed mode. So back to the question, which Nvidia starting from the equal rival and upwards to i guess the 580 and above? If i find a reasonable card at a reasonable price i might sell mine and put in a little extra cash to get an nvidia.Thank you
