This was my first build and I am glad I did this instead of buying another prebuilt. This destroys any prebuilt at this price line. So far I have no issues with it. My younger brother is getting into video editing and he is using it as well. No issue there either. I use it for gaming but i have no major games to test the build yet.
If I had to go back, I probably would have just gone straight for the 390X, and a smaller case. The case is awesome, very quiet and great airflow, but it is a giant! In the future I will get a 4K monitor and I will get a better graphics card at the same time.
