Thanks all of you! Considering your different advices, I will not upgrade my GPU.

Thanks for your answer!

I thought that i7- for simulator games was alsmot a very good CPU and the most important was the GPU.
Reading your point of view, I will not upgrade my PC and perhaps buy a new one in two/three years.

Any other opinion?

HI everyone! I use P3D v3 on my PC, and I will certainly buy and use P3D v4 in the next future. I mostly fly PMDG 737 NGX or MJC Q400 with ORBX BASE + Vectors + openLC + Trees HD, GSX, ASN, Chaseplane, fs2crew. And of course, sceneries for airports such as Jetstream LFRS, Aerosoft LEPA, etc. Perhaps...

Hello!

I will buy a new PC to play with P3D.
I hesitate between two processors: i5-4690k and i7-4790k. Which is the best for P3D and why?
Does P3D use multi-cores and hyperthreading?

Thanks in advance for your help!
