I wanted to clarify what and why I was asking the above questions.
1. I was asking because I wanted to know what is possible with the new Nvidia drivers and Lion 10.7.3.
2. I wanted to know if I could replace the original ATI Radeon HD 2600 with the Nvidia GTX 550 Ti to, at least, get Resolve Lite running.
3. I have read the Resolve manual before I asked the original question. So, I’m aware of what the manual says about which cards are recommended (gt 120, gtx 285, HD 5770, Quadro 4000 etc).
4. I was wondering if Resolve Lite could be run on with the Nvidia GTX 550 Ti, firstly as an upgrade for the ATI Radeon HD 2600 and secondly as a GPU and addition to a GT 120 as the GUI.
5. I’ve asked this question in the thread discussing the new Nvidia drivers but no one answered so I asked here.
