The title says it all. If the 970/980 didnt come out last year people would still be saying the 780 is the best card for fsx. So which one is it if were talking about just fsx and not other games.

780 has more beef in the memory interface - 384-bit versus 256-bit on the 970/80.

 

What it means? Probably better performance with higher resolutions, i.e. 4K.

Additional reading says the 980 does better with less. I went the 980 route. Not dissapointed.

As a user of the 780 for my simulator & my career, I too hopped on the 980 train and I must say I am very pleased. IMHO I actually go as far as calling it a night and day difference on my system.

 

cheers.

so i guess the memory speed and clock speed make a difference, because the 780 beats it in texture fill rate and a couple other things i think

Not in my opinion and testing, no. 

 

Only thing the 780 beats it in are CUDA cores (won't get into that because you said to keep it JUST FSX and FSX uses no CUDA cores) but it makes up for it with a high base clock.

Which adds to the point that LAdamson said, by the card doing more with less (especially power)

 

On my system and my opinion I confirmed a pretty hefty FPS increase when I upgraded to a 980 (I would also like to add that I'm a P3D user and not an FSX)
