i7-4790 vs i7-4790k

My current CPU most works 'just fine' - a several year old AMD 965.

But I have a little itch to think about a current system - I do have some performance issues at times, whatever the cause, and it's tempting to want something without them.

Right now, I have option to buy an I7-4790, which Google says it almost twice as fast, for $250. But then I noticed the i7-4790k, which is going for $300.

I hadn't looked at the k because it said 'for overclocking' which I don't do, but then I saw it appears to be about 14% faster just at base speed.

It's a little hard to pass that up. So... 4790 for $250? 4790k for $300? I asked before about 'or wait until later' and the one reply said just buy now.

According to intel, the 4790 base speed is 3.6, while the 4790k is 4.0.
I'd pay the extra and get the k.

I'd say get the 'K' model. More clock speed and allows you to overclock should you ever get the itch to do so.

In this specific case, the normal rules governing the choice between K and non-K do not apply. The 4790K is faster out of the box, and as of now has the highest performing stock clocked cores on the planet.

With the right mobo and MCE you can load the 4790 to an even 4.0GHz across all cores on load, negating some of the clock speed differences. For $50, up to you.

Ah. . . "multi-core enhancement." I almost thought to make a Wiki. Truth is -- I'm playing with some Z77 boards right now, and wondered "what the hell is that?"

I'm no good for advice about this. I was bitten by the enthusiast bug around 2003/2004. Before that, I just "built computers" and I would low-ball the parts budget. If it were my rig, I wouldn't blink while I paid the extra U.S. Grant for the K.

If you're changing platform, with a lowball for mobo and RAM of $150 that's $450 vs. $400. At that point it's basically even on performance for dollar so practically unless you severely cheap out on mobo and RAM the K is going to be better for performance per dollar. The question of course is whether about 1/8ths more performance for 1/8ths more price is worth it to you, or if you're price limited whether that's the most effective place to spend that $50.

Well, the good news is, for all the votes to get the K, Amazon customer service is kind of crazy good on this, and I got the K for $250. Best of both worlds.

Now, will I hold on to it for years like I have? Not a good idea, probably need to make one of those posts for other parts and find a local person to build a new PC.

I was thinking hard of one of those 1TB Samsung SSD's, but the $350 pricing ended.
