i5-2500K, why is it so "amazing"?

post #1 of 21
Thread Starter 
So I'm not really that experienced with PC components and stuff, but why are people so in love with this CPU? What makes it different from say, an i5-750? Is it a dual or quad core CPU?

And what does "unlocked multiplier" mean? I need a new CPU sometime soon, and I was wondering if I would see a decent performance boost switching to an i5-2500k from a Phenom II x4 965 BE. Note that my 965 BE is at stock settings, but I hear you need to overclock the i5-2500k to see its true potential.

It's a quad core. It's incredibly inexpensive for what you get, and the unlocked multiply means it's stupidly easy to overclock to what was once considered a pretty obscene overclock.

At the moment, it's likely the best bang for the buck and for gaming purposes, it is nearly as strong as the core i7 2600k (negligible differences).

But I have also heard that if you want a good Motherboard for the Sandy Bridge socket, they are quite expensive, and the cheaper ones don't work too well. I honestly don't plan on spending more than $120 on a MB, so would this CPU be alright for me?

Also, exactly how easy is it to overclock this CPU? Could someone like me with almost no overclocking experience be able to do it?

Not true. Most P67 boards are more than suitable, and I haven't heard of too many that make a truly significant difference in overclocking. From my understanding, a better overclock is usually determined by luck (getting a nice CPU by chance) and the kind of cooling you're willing to put into your system. Most boards are equipped with enough of the good stuff that those will be the only two things you'll have to worry for a decent overclock.

If you do decide to go through with this, just make sure the board you buy is a P67 and not an H67 board. H67 boards cannot be overclocked through the unlocked multiplier.

You can get some very nice p67 boards for 120.

Edit: There are also some very nice articles on the forum about overclocking the second generation core i5 and i7s that are currently available.

Overall, P67's seem to only vary after you break the 5-5.1GHz wall.

You shouldnt have that much trouble finding a motherboard for about $110-130 price range for sandy bridge, just be sure to get a p67 (or the upcoming z67?) motherboard if you plan to overclock. The h67 boards let you use the integrated graphics but loose the ability to OC pretty much. And overclocking should be pretty easy just refer to some guides here or post a thread if you need help, its when you start to push the overclock it might be a bit more tricky, but thats what ocn is here for

What about RAM? Right now I just have A-DATA DDR3-1333 RAM. Would that be suitable for OCing this CPU, or should I upgrade to G.SKILL?

Also, will I notice a difference in speed with this CPU if switching from my Phenom II x4 965 BE?

Best bang for you buck CPU available at the moment if you want max performance. (because it can easily be overclocked to 4.5-5.0+)

At stock settings I don't think you'll see a huge difference compared to your AMD cpu it all depends what you use your setup for. My previous CPU was a pentium D 940, so the difference is huge...

The ram will depend on the motherboard you choose; they (motherboard manufacturers) have ram compatibility charts on their websites.

When you overclock sandybridge, you don't normally overclock the RAM because it's all done by the Turbo Multipliers for the CPU. The BCLK only goes up 5-10mhz tops so most people don't bother with raising it.

I can't confirm the speed difference because I don't know much about AMD products; thus, I don't know what is currently your computer's bottleneck.

Your ram should be fine as long as it is DDR3 and below 1.65 volts. It is recommended that you should use 1.5v or lower for the 2nd generation platform, but most people seem to just take this as a serving suggestion.
