Question Which OS to maximize performance?

[StupidComputers]

Debating which os for a couple of rigs for max performance, as well as overclock recommendations

965 on 880gma-ud2h w/Arctic Freezer Pro 64 (92mm)
8gb 1.65v ram @1333 9-9-9 or 1600 11-11-11 PGD38G1600ELK (can't find a way to push it stably to rated 9-9-9-24 AMP/AOD-BEMP not available on 880)
antec ea350w, hd4250 igpu, ocz vertex180 120gb ssd

currently on win 7 pro x64, which is not as snappy as i had hoped, but that could be Comodo's fault (CIS "premium" lol freeware)

1090t on 890fxa-gd70 w/Scythe Mugen 2 rev b
8gb of same ram, still putting it together, no os (thinking W10 pro x64), checking what i can do with ram from bios soon, will update.
currently on CM 450gx, wd2001(fass?) 2tb hdd

there are two gpus at present, gtx 460 and gtx 560

one is going to be a basic use computer (probably 965/880)
one is going to be a workhorse/streaming dedicated rig (probably 1090)

I've got a line on cheap parts from this era and im open to any hardware switches or purchases (cheap)
I've got a quote on a gtx 680 for $70, which is more than i want to spend, and probably dont need.

I've also got a Noctua nh-d15 on my 4790k, but I really dont think switching it with the scythe would be a smart move...

I don't see much call for not using Windows 10. Windows 7 only has 1 year left for updates.

Basic use computer, web browsing and stuff, nothing wrong with Ubuntu or an X-Windows distro.

I don't know enough about streaming to say, but you might see some drop off for Windows 7 support soon.

all the 9-10 year old AMD processors are going to be considered slow on Win10 by most folks, so, I'd stick with WIn7 thru it's final year of life until finally retiring the rigs, or, at least retiring WIn7... (Linux will last a bit longer on this hardware)

Might as well opt for 6 cores if doing any work, as both CPUs run the same clock speeds...

I hadn't considered linux, the basic computer is for people who know nothing about computers so a familiar windows is pretty much a necessity. If I can use linux to stream the output from a win10 pc over lan (no capture card), that would be pretty sweet.
