How cpu/OS systems work on cores

[BootyChief]

Hello everyone, so i heard league of legends only uses two cores being 0 and 1. So as to my question, assuming you only have a DUAL CORE chip the operating system would be forced to use the same cores as league right? But if the chip had hyperthreading, would the OS just sit on threads 2-3 and the game on 0-1? Also if you have a quad core chip, would the os be running on the other cores or the same? Cause if the cores dont matter cause i dont multitask then i may aswell just get the 7350k once the price drops a fck ton cause the new lineup. 2 super fast cores is what i need. Sorry for the poor english LINUS is rubbing off on me ;). Looking forward to the responses.

The way threads are "assigned" processes isn't a that simple as demonstrated by this lovely photo:

 

Often you'll see that the workload isn't spread out evenly across all available cores. That's how complicated this stuff is.

Prices don't tend to drop with a new lineup, unless you're looking at the used market.
Hyper Threading wouldn't "move" the OS to threads 2 and 3. It doesn't really work like that. But for all around performance you're gonna want at least a dual core with HT. A true quad core would be optimal.

Pretty much nobody bought the 7350k, so rip that idea. AFAIK the OS tries to split processing load evenly across all threads, so having other light programs open while you play league shouldn't be an issue as long as you >2 threads.
