Upgrade iMac 27" late 2009 to El Capitan

[skrondo]

Hi!

This question torment me for months: should I upgrade from Mavericks to El Capitan with my glorious iMac 27" Late 2009?
I've made some tweaks during years, here the info:

Processor 3,06 GHz Intel Core 2 Duo
Memory 16 GB 1067 MHz DDR3
Graphics ATI Radeon HD 4670 256 MB
Fusion Drive with Samsung MZ-7TE250BW SSD 840 EVO 250 GB + 1TB HD (this is the tweak)

I've read that time ago ElC will have problems with homemade Fusion Drive, is right? Can I reinstall from zero without troubles?
I use graphic software (Ps, Flash), will speed up or lag?
I use notes (on iCloud) is true that will delete all of them? Will Notes sync with my IOS 8.4 devices (iPhone, iPadmini) ?

All my best wishes for every answer

I have no answers for you, but I think your question is more about hardware than OS X. You might get more responses if you moved your post to the iMac forum.

I have a second iMac that is late 2009 with El Capitan installed on it.
Truth is - I don't use it very often, but as far as I can tell the iCloud services work just fine.

Make a time machine backup of your system first - and just install it and see for yourself.
