As this is more a discussion I am going to shoot my fears in here. Do not worry, its Win 10 related 
Currently I have fresh(ish - 6 months) install of Windows 7 64 bit on my rig. The specifics are :
FX 4300, R380 2GB, 16GB DDR3 RAM (4x4 DualChannel), classic SATA 3 HDD (yes, no SSD... yet)
I have some minor issues with AMD Crimson drivers (well... we are in open war, but I have the upper hand
), but otherwise its superbly fine (for the hw used).
The rig is for mid-end playing and for the titles I play works like charm. That narrows my question - should I upgrade to Win 10? Can I expect some benefits from the new OS? I mean yes, newer DirectX, but... I really use DX 11 titles so far, and I am not confident that my rig would keep the pace with new DX games on max settings (only there it would matter)...
Or would it improve my AMD drivers experience?
Because this rig is a gaming platform. I am not impressed by better look, better search and windows store. I do not care about that. What I care is best environment for my games. For Steam, for GoG Galaxy, Battle.net app and Origin app... I actualy do not care about improving the OS bootup neither (but any improvement wont hurt on the other hand). I do not care about MS Office stuff neither, nor any cloud solution... For work I have Linux laptop which suits me better... for work
So.. My question should I, with the rig I have, move to Win 10 and earn something valuable for me in the process? Or should I stick to proven and working OS, as the upgrade would bring me nothing or even some headaches? Complete fresh reinstall of W10 after upgrade would not be welcomed, but it is possible for me for sure
Thanks for hints...
