If you can spare the little extra, do yourself a favor, drop the GTX 750 and get the 970 (980 or 980ti if you can handle the wallet hit).   The process is very solid that and is the new Go-To processor for the flight sim community.

I surely have considered building my own, however I have come to the conclusion that I would need more time than the only Saturday afternoon that I'm off to view all the tutorials and build it myself etc...

 

Alternatively I had the boring idea of just giving my local PC store the specs I want to get and let them build it for me, however the working hours i would have to pay the staff for building it would not be worth it in the end.

 

So I continued looking and caught the attention of another custom build PC the following specs:

 

 AMD FX 8320E Octa-Core Processor

 16GB DDR3 RAM

 2000GB SATA-II HDD

 NVIDIA GeForce GTX 960 

 ASRock N68-GS4/USB3 Mainboard

 

Now what I'm looking for is basically included.

 

Is there anything else I need to be aware of and look out for before I actually finalize my purchase? 

 

This is not what you want... neither the CPU nor GPU is a good match for flightsimming..

 

As others have said, the right combination is Intel i7 4790K or better and Nvidia GTX 970 or better.

Intel cpu only for fsx or Xplane just AMD product line can't even beat i3 and g3258 cpu at single thread cycles.
