My new computer

If you're planning to overclock, I'd go with 3770k. The new Haswell processors produce massive amounts of heat when overclocking, so you'd need a really good cpu cooler

That's not correct. Sandy Bridge was colder when overclocking, Ivy hotter. Haswell is in between and it's not something to worry about. Forget about it.

@ Smoke: Yes, if you have a 1TB HDD then a 120GB Samsung 840 is great. The only difference between an i5 and an i7 is Hyper Threading from which you won't benefit unless video editing. If your concern is games, there won't be any difference (maybe a very slight one at the moment). When games start to utilize more cores, then yes.

Now for cpu cooling there is water & air. Water is always better but more expensive and sometimes noisy. Since you are not an advanced user and won't really push the overclocking capabilities of the cpu that much you can buy a good and silent air cooler. Do you care about silence?

With overclocking you get free performance in expense of power consumption & heat. Totally worth it. It needs reading though at first and time. Just so you know.
