They're both around the same price, in fact the ivy bridge is slightly cheaper at the moment. I am leaning towards the ivy because it's the newer model although, I have heard it does heat up a lot more than the sandybridge which is a little worrying.
So my question is, which of these two CPU's should I get?
if your going to overclock go with the i5 2500k, it overclocks higher. i would recommend a 3rd party fan.
there both very good and advance processors, anyone you pick, your going to have a very good build.
Yeah, I'm not totally sure if I will overclock or not. With my luck I'd probably fry the whole thing. Is overclocking really worth the performance boost? And does it potentially shorten the lifespan of your parts? I know very little about it
Overclocking does shorten the lifespan of all parts that are sensitive to heat, which is most if not all. If you overclock, pay the extra bones for a quality aftermarket fan to cool everything down. Most parts manufacturers (CPU, GPU, RAM, HD) try to aim for a 5-10 year lifespan for parts and if they aren't properly cooled, you can count on halving that.
However, if you are the kind of dude who upgrades every two years anyway, it's probably not going to be an issue anyway.
if you don't know what your doing, i wouldn't recommend overclocking just for that extra benefit. It doesn't shorten there lifespan if your doing it correctly. just make sure you have decent cooler and airflow. you should be fine.
I own the ASRock Z77, extreme 4. At the time I was thinking possible crossfire/SLI. I am no longer interested in that ... too much pain, not enuff gain for me. I'll just buy a better GPU when needed.
What I would do now would be the ASRock Z75 Pro3. Again, it's about $50 less and has everything I'd need.
Did some newegg.com research after my first post. Looking at the reviews most motherboards appear to have about a 10% failure rate for various reasons including install issues ... I'm a noob and my ASRock experience has been positive to date.
Buy and SSD for your operating system. You'll love it.
