My system is :
Mac Pro 8 cores 2,8Ghz
5GB Ram
Graphic card for UI : ATI Radeon X2600XT
Graphic card for power : Nvidia Quadro FX 4800 1,5GB
My project is in Prores 422 HQ 1080p.
Even with one node with juste one key and one power window, i only get 17 fps.
Is that normal?
What is the best way to upgrade my system to have real time?
Sounds like you have a Mac Pro (early 2008), version 3,1. Ola may have the solution regarding upgrading the graphics card. Dan may be right that the CPUs are lacking in horsepower. It is say showing its age compared to the power of even recent MacBooks and iMacs. One option, if you can tolerate not having real-time playback, is waiting about a year for the 2013 Mac Pro that Tim Cook confirmed is coming.
If you can't wait, Resolve 9 is now 64 bit and may be demanding more memory. Have you ran Activity Monitor during playback to see how much free memory you have? It will likely be paging and swapping memory and that slows your performance. You should ideally see a swap size if 0 and no page outs. You could upgrade memory to 16 GB but that will be quite costly on an older computer.
You could also try using an SSD for your internal drive. Do you have a lot if free disk space in hour drives so they are performing up to par? Activity Monitor can show you your access speed to the disks. If the disks seem very busy but you are not getting much performance, they may be too full.
These are costly and may not get you to realtime if the CPU is lacking. Again Activity Monitor will tell you if you are maxing out the CPU during playback.
Let us know what Activity Monitor is reporting. Unfortunately it doesn't tell you what resources the GPU is using but it can certainly help with CPU, memory, disk activity. It may be a combination of things that doesn't justify all these upgrades if you are considering a new machine next year.
