P3D needs a proper Nvidia profile before the AA can match that seen in FSX.

I have used my new system now for a week. In short, I think it was worth it, all though the sort of evolutionary improvement rather than revolutionary might not be worth 2000 euros for everyone. Btw I overclocked the Haswell easily to 4,6ghz with a Noctua premium cooler. I have done 4,7 and 4,8 also but with some crashes. However I just did Asus autotuning so might be more headroom with a little bit of manual tweaking expertise.

 

FSX has never looked better. The 780gtx card displays the scenery so beautifully. I can crank up the AA settings,  and get super clear images with minimal shimmering. I am getting 30 fps locked at big payware airports, like Dubai, Thessaloniki, Gardermoen with PMDGs. I didnt get that before. 

 

As was kind of expected I am still not able to enjoy 30fps flight with PMDG in major urban centers, such as London and Paris. Then I need to dial down the autogen settings.

 

Prepard3d v2.3 also performs just as smooth, if not smoother. But the one thing that keeps me from singing the praises is poor antialiasing. I would say that FSX looks way better in that department, allthough shadows and lightning in prepard3d is better.

 

I still havent implemented Nicks FSX tuning guide, so I am hoping that could boost my results even more.

 

Now I am considering to upgrade my monitor from 27" 1920 to Asus 2560P, or potentially a 4K monitor. How much of a frame rate impact would I see?

 

It's good to hear that your upgrade resulted in such a significant improvement, as I was sure it would.

 

I'm looking forward to getting the same cpu and video card in a few months.  I'd really like to be able to utilize transparency supersampling to reduce autogen shimmering, but my GTX 670 just can't quite handle it (frame rate drops to <20).

 

4.6GHz is pretty good.  I'll be happy to run at 4.5GHz.  The increased clock speed, plus the performance improvement gained by going from a Sandy Bridge to Haswell, should result in an overall 15-20% performance gain.  Couple that with going from a GTX 670 to a GTX 780, and I can't wait to see the results for myself.

 

Thanks for posting your results.
