I would strongly advice against the V300. Kingston has been caught swapping hardware in it, dramatically reducing its performance.
I would also step back from this monitor, it has bad reviews, mainly about poor viewing angle.
Swapped the FX to an i5 - The 8350 would surely perform better than the i5 for video rendering, but not for gaming. It would have a hard time running Arma 3, and other single-core performance hungry games.
Included better video card and wireless adapter.
