Pro audio computer(PC)

Hi guys,

I need your help regarding a system that I’m about to purchase.

First of all, my studio workstation based on a synthesizers and drum machines.
I will not use any VST and the only synth that have a VST is the Virus Ti 2.

I will use some lite plugins for Delay, Reverb, and Stereo Expander.
I will use the UAD-2-SATELLITE-DUO for mixing and some mastering.
I will use the TC electronics Finalizer 96K for the mastering processor.
Cubase 8 as my main sequencer and RME FF800 as my audio interface.

I have built a PC that fits my budget, but I will consider an upgrade if you guys advise me. Please note that the system will have acoustical treatment inside.
