Thank you for answer, I hope you're right and this upgrade could work for me too; I was even thinking to purchase an r9 270 or 280 for its lower price but maybe i must surrender and accept nVidia as the best choice for FSX. So, do you think that 760 is good enough for, at least, keep my current FPS and run smoother? Maybe a 770 is better but is out budget for me...

Hi simmers, My system specs are: CPU: i5 2500k @4.4GHz; RAM: Corsair Value 1600MHz; MOBO: AsRock z68 pro3-m; HD: Samsung SSD 840 evo; GPU: XfX HD6950; Now i'm running FSX with many addons (NGX, 777, FS-GLOBAL etc) and after several tweaks and optimizations (cfg tweaks, Shader mod, balanced settings etc) i got avg 25 FPS; My only problem is smoothness: even with an ssd, when turning on ground or taxing i often get some stutters (like a micro-freeze) i can't get rid. It's very frustrating. I suspect GPU is my system bottleneck, saw that GPU load jumps often over 80%. So the question is: upgrade from an AMD HD6950 to a Nvidia gtx 760 or 770 could improve the situation or is it a waste of money? Thanks for your help.
