2 SSD Sandisk on PCI Sonnet Tempo Card For Samples & Libraries Kontakt

4 HD internal

RADEON 7950 Mac Edition Video Card with 3 screen Samsung Curved


The problem is when I have a large session with ten VST instruments Nexus Kontakt ...

and Plugs from UAD with PCI EXPRESS DUO CARD and others


The mixer vu meter have strange reaction slowly reacting like not enough video memory

the cpu is 60 % used in the cpu Performance Cubase

so I don't Know if I can get better GUI or video performance buy changing the video card for a Sapphire Radeon RX 580 Pulse 8 Go

and upgrade my six cores two 12 cores 3,46 ghz with more ram


or simply changing my Mac for a new But which ?
