I was using a core i5 Haswell system built 4 years ago, and finally made transition to AMD ryzen series.

This is my first time using AMD Processors, and I must say, they are really fast and runs very well in almost any games in these days.

I haven't tested FSLAB A320 , since update hasn't been release to v4.1 yet , but so far, I am loving with the system. 

Everything was set to default and I just play around with HDR . That's it. 

My GPU is GTX 960 and proably I am thinking upgrading either 1080 or 1060.  Personally, for FSX or P3D, I think you can use almost 

any CPU if you want, the important part is your GPU.   

 took a screenshot of the normal gameplay in p3d.  Hope this helps.   I think I understand why people praise about 1600x .  

By the way,  I am gonna build a 2nd PC just for FSX.  or it could be STEAM/Stream gaming for Ryzen 3.   

 

 

 

 

I'd say either a GTX 1070 or GTX 1080 should work fine, If you've got the budget, go for the GTX1080

This might be a good starting point for a decision

mainly , I havent catched up on hardware these days  since I am in kind of software field, 

but looked at the price at gtx and  omg ....and gtx 1080 cost like half of it 1060 

 ...I dont have problem playing with gtx 960....they are fine 

but sometimes I have to play in mid option in battle field....

I have a GTX1080 and run Concorde in P3D v3.4. But crucially, I run at 1920*1080. If you plan to run at 3840*2160 (4K) then the graphics card will become even more important. There is bound to be a fps hit at 4K but I couldn't tell you how much.

With all your recommendation, I was able to get gtx 1080. 

to me, from gtx 960 to 1080 is way good upgrade. ofcourse 1080ti

performs better they cost almost 40% more with 40 percent performance 

improvement.  for now I am satisified with 1080.  

I have played them on 4.1 they run extremely smooth, I never played 

p3d smooth like this before.
