Mac Pro 3.1 upgrade 2016

HI there,

is there any favorable upgrade I can give my Mac Pro 3.1?

until now I've still been running OS X 10.5.8

I had to install 10.7 on a pny cs1111 ssd I got to repair my old system, which worked.

i was having issues upgrading hardware due to software I was not willing to upgrade, as it worked just fine (which wasn't supposed to change).

I've read through many threads, but still could not conclude which options to take advantage of, for upgrading my Mac Pro.

are ssd safe to use now? Does the trI'm function work.

another issue I have upgrading, is that I'm using a yamaha 01x, which only seems to work 32 bit. Found the hold 3 and 2 key down solution for that, which is fine for me, rather than investing in even getting an equivalent sound device.

Logic Pro seems to be upgradeable all the way, still working on OS X 10.7, which I'm trying to use due to the trim function I need to run the ssd, as far as I figured out.

i also read about the newer technology raid card which might just make my i/o's really fast, but then again I live in germany and I can't seem to find the mini das extender cable here in shops, to actually connect it right.

Most of the upgrading threads I read, don't give conclusion, if the upgrading actually worked stable for longer, which is my goal.

i Would like my Mac to become more safe (trying to find the best bad up solution too) and faster.

Btw. mostly I aktually work with Adobe cs products and Logic Pro.

i hope this all still makes sense. And I will answer any question that may help my quest, in case I have forgotten to mention details needed.
