Hi all good people, new to this thread and i really needed a quick answer without browsing through 192pages to try finding the answer

.
Has anyone installed Sierra on a Macbook Pro 17" mid-2009 2,8Ghz (MacbookPro 5,2)? I am thinking of installing on my machine as I've just upgraded to the max 8GB RAM.
Is there any problem you've encountered as of now? The impact on battery life & performance?
Mainly using my macbook for multimedia producing/editing (PS, AI, Logic Pro X, FCP X).
I've been staying on Mavericks for so long due to concerns of performance issue on newer macOS, but my existing apps updates kinda pushing me to the need of upgrading to at least El-Cap.
