I'm of the opinion that although Platinum has more bells and whistles than X3e Producer it still isn't even half as solid or dependable, and that really pisses me off after a year of Platinum 2015 updates that translated into nothing more than; "Oh yeah baby, we're almost there, so keep your subscription running or you won't get any fixes, you beta test porch monkeys!"
I'm sorry, maybe I'm feeling bitter because I feel like I've been mugged because Platinum 2015 utterly bugged out with the Windows 10 Pro (Redstone) "Anniversary" update, Rapture Pro no longer runs standalone, and ever since I upgraded my aging audio interface to a Focusrite Scarlett 18i20 Gen 2, SONAR Platinum 2015 hangs up for 20 or 30 seconds every time I hit the space bar or stop on my MIDI DAW controller. Yeah, so am I to assume I'm held hostage to a never ending subscription plan packed to the gills with a supply of **** I don't want or need to have this condition solved?
Thank God I never uninstalled X3e PE.. Still working GREAT after all these yeers, and seems to be the only alternative I have to actually getting any REAL work done in respect to actually performing and recording music, as opposed to trying out all the new bells and whistles. ;-p
I switched from AMD (like you, a similar build) to an Intel build I7 and platinum is solid as a rock here.
my drivers used to hang in X3 (my Focusrite (like yours) the drivers wouldn't release so recovering from a crash to ages. however I did notice a change while still using my AMD with drivers being released in platinum Cambridge update.
man I do hope you find peace with your daw and platinum. I can feel for users who have had problems running DAW software, ive been there man, it stinks. I thank my lucky stars I have little to no issues at all right now...well except certain features I wish were there (my own feature requests) like colored strips, track templates that could be used on existing tracks.exc..
but for the most part, platinum has been a life saver here. it is funny the software works well for some but not as well for others.
that's the difficult thing about designing software, your not going to be able to please everyone.
I hope you take that with a grain of salt man

.
what might be a problem for you I don't have..what I might have a problem with...you might not.
that's not always easy to design. good luck.
