Well, I did ask for more information, but you said we didn't need it. Feel stupid yet? That's one of the reasons that info is handy to have, huh?
The difference is going to be when he OC's by ~1Ghz, if he so chooses, and suddenly kicks massively further ahead. You lose a TON of OCing headroom with HT.
Obviously, if he doesn't want to OC, things get different. Again, that's why I said more info would be good, but you decided to attack based on me going from incomplete info, and assuming best case scenario.

We don't need it, because an i7 2600 and its quicksync is more than enough for anybody by itself. Overclocking is for enthusiasts who want to put the time into it.
Recommending an i5 for any kind of heavily multithreaded task is stupid. You needed to be called out on it.

Overclocking is for anybody who wants better performance on CPU related tasks. If they're willing to do it, it makes an i5 2500k a better choice than an i7 2600 hands down. Trying to tell me the information I asked for is irrelevant and attack me for not having it at the same time is completely fucking moronic, so maybe you should back off. It's all guesswork until we get more info, which probably makes me less stupid than you, huh?

The i7-2600k typically overclocks higher than a i5-2500k anyway, probably because of the higher binning? Any time a review (e.g. 1, 2) looks at both using the same setup, the i7-2600k seems to go up a little higher or reaches the same frequency. Unless you're increasing voltage significantly for the overclock, a i7-2600k isn't going to need more power than a stock Bloomfield, so it's not like cooling the i7-2600k would be too challenging, even if it takes more than the i5-2500k.
Anyway, I'd assume somebody getting help for a build for those tasks probably wouldn't be overclocking anyway. On that budget for rendering and video editing, paying for the hyperthreading is probably worthwhile. As a convenience I'd suggest an SSD for storing those programs too.

And if you think you can hit the same OC's with HT still on as without, stable, on typical cooling, you're smoking some amazing shit. The voltage needed for HT at a heavy OC is insane, too, and may be too much for a lot of motherboards.
HyperThreading is hot.

Okay, I'm not 100% sure on if he wanted to overclock or not, but I'm assuming he would be open to doing so. Resolution would be 1920x1080. And I forgot to mention that he does like streaming if that makes any difference.
And that should be everything important. I'll let you two get back to debating the 2500k vs 2600.

Well, it's your friends build, so it's his call. Either one is going to work well enough for his needs, it basically comes down to how risky he's willing to be with the OC, since the HyperThreading is hot as hell and runs higher voltage. If he's willing to really work at it, the 2600k will probably top out slightly better, but the 2500k won't be as delicate at the high OC.
I won't argue that in the end, the 2600k can top the 2500k, but it's a lot hairier to hit the insane clocks with HT still on, so it's likely to end up not being a big difference if he isn't willing to go the extra mile on it.
Basically, to get it to similar sorts of clocks and then stabilize it with HT, you're going to be running some pretty abusive voltages. If you downclock enough to not need a ton of voltage to stabilize the HT, you might well reduce the benefits from HT to the point of not making much if any difference.
I haven't had the pleasure of abusing Sandy Bridge that way to be sure, but with my Bloomfield, that's pretty much the case.

I talked to him and asked which processor he wanted. He did say the 2600k. What else would he need with that to keep it from overheating if he wanted to clock it at something high like you are saying?

As posted earlier (granted, using better than budget cooling and motherboard)

And you'd need a whole lot less frequency to compensate for the difference in clock speed attained.

Anyway, if overclocking is an option, on that budget, take the i7-2600k. That's what it's for.
edit: I'd get a Z68 motherboard in case Quick Sync becomes more useful later on. They're not much more expensive. Most of those should be able to get a i7-2600k to the 4.7 GHz range or so. Most generic $30 120mm fan tower coolers should be enough for that kind of overclock too. However, I'd think something around 4.4 GHz that needs no voltage increase or a minimal one, is more realistic for long-term use and should be good enough. Cooling and motherboard requirements for that should be fairly low too.

Nevermind, looks like most good aftermarket coolers will work. Bloody efficient little high end CPU's.
Edit: Wow, those things are way more polite about that than my 930. Guess that's what happens when you try to extrapolate from a less efficient CPU.
Although going by that bench, I'd say my original statement that got me attacked, suggesting an i5 vs the AMD hex core, was still actually correct. Damn. Looks like we both get to eat a few words.

If you're asking this question, the odds are good you're not likely to use that much.

Go for it. Ease of mind.
Don't spend your life going, what if I ate that pie? Go take the pie and eat it.

Posted on my other thread but no replies
"
I was playing SC2 and then I alt tabed, to turn on a youtube video.
Then after around 3 seconds into the video, my computer froze.
At this point I was alt tabbed in the game. I don't know whats wrong.
I pressed restart button, and now whenever it boots, it won't go past the motherboard screen. "AS-ROCK BLAHBLAH WITH IMAGE"
Side Note:
I bought a brand new mobo, cpu (i3-2100) a week ago.
My Hard drive on the other hand is about 4 years old.
(The trouble of my computer freezing always happend whenever I would watch Youtube but it would fix itself when i restart my comp, But this time it's weird)
Any ideas how to fix? is my Hard drive gone? what about any other parts like cpu they are not affected?"

My friend would need an HDMI out on his video card by the way.
+ Show Spoiler +
He needs the build for his video editing, streaming, etc. Read earlier posts if you need a bit more detail. That's his build as of now.

Pretty much this.
What was the point of asking, if he knew he wanted an i7 2600k?

Like I mentioned earlier, I'd get a Z68 motherboard instead, like this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157251
That way Quick Sync is available. The whole integrated graphics and video transcode hardware in the Intel Sandy Bridge processors can't be used with a P67 motherboard. On a side note, this would also provide an HDMI video output, from the integrated graphics.
Figure out what software he's using, to see if a workstation graphics card would actually help. That kind of thing can always be added later.
For $10 more you can get a case with a more modern layout and conveniences like the HAF 912. Maybe you should just look around or ask what kind of case he'd prefer.
