I'd lean towards turning it off if I were just gaming and/or overclocking.

I was only impressed with HT with the early P4s. Now it seems to benefit their marketing more than the servers. but what do i know

Hyperthreading is only useful to encoding, editing and other cpu intensive applications. Furthermore several applications within those groups are often not optimized for HTing so it can actually slow them down, but that's more the exception than the rule.

If you are just gaming and watching movies I'd say HTing off.

it makes no difference on these CPUs for OCing if you turn it off most of the time, leave it on, that is why you got a 2600K over a 2500K and paid 100 bucks more.

hyper threading is useful all the time if you multi task. Its not some type of firmware or software.

How, exactly, is it useful? In what ways will I notice a difference with it on if I'm multitasking? When you say multitasking I assume you mean regular everyday stuff like web browsing, word documents, etc.? As in, things that raise CPU usage of an i7 to, max, like 5%? How will HT help?

No, heavy multitasking is not the everyday e-mail or youtube.
Example:
I have 2 projects of VisualStudio open at the same time, 1 SQLServer, 1 WindowsMediaPlayer playing some music ( \m/ ), 3-4 tabs in the browser, each showing some animated ads, HWMonitor to see my temps, Windows sidebar and some messenger to talk to my wife.
That is about 10-15 threads total, each (or at least most) doing something intensive

there is one point. higher overclock stability. in other words, electronic-penis.
