I recently upgraded from an AMD 955 CPU to an i5 3570k CPU, and I must say that Intel has gained another convert. This CPU will chew through any game, and I get much better performance than I ever did with the 955--the 3570k simply blows AMD out of the water. I do not do any sort of image editing or video encoding, so this review is written entirely from a gamer's perspective.

-Great for extremely CPU-intensive games like the Total War games (Empire and Shogun 2 in particular). These games are fairly difficult to run smoothly at very high graphics settings due in large part to incredible (but demanding) particle effects, high unit density, shadow effects and many others, but the 3570k has no problems handling Empire at max settings (assuming you have a decent GPU to boot).
-I get much higher frame-rates and better performance in games like Crysis, Crysis 2, BF3, Max Payne 3, Empire: Total War, and Deus Ex 3 as well as older games like FEAR, Half-Life 2 and Rome: Total War.
-Achieves an overclock of 4.3-4.6GHz without much trouble at all (I've got mine at 4.5 GHz), at least on a Gigabyte Z77-UD3H motherboard.
-Using the Gigabyte Z77-UD3H MB I managed to OC to 4.3GHz with no stability issues at stock CPU Vcore voltage (1.13 V).
-Built-in Turbo boost feature clocks the 3570k up to 3.8GHz--which is a pretty decent boost and would be a good option for gamers who are uncomfortable with messing with BIOS settings to OC their CPUs.

-Almost identical to the 3770K in terms of gaming performance. Benchmark scores for a number of games show marginal (if any) improvements for the 3770k. Other benchmarks and certain games like the Total War series actually see improved frame-rates with the 3570k versus the 3770k.

I am very impressed with this CPU. "Slick" is the word that comes to mind. THe stuff on paper about the native PCIe rev.3, and the new memory control circuit....etc. It looks good on paper. "These numbers are better than those numbers, this is different than that...." Well I put one of these into my computer...the one I use everyday, and haven't really upgraded for a while. I build i7s and Xeons, opterons, and Phenoms.......everyday. I get them to work, feed them an OS, drivers, applications, burn them in, package them and ship them out. I never really do 'my' work on them. (kinda like the shoemakers kids). I went back and forth between the i7s, the 2011 socket....but since this had been a bare bones bullet proof unit, I decided to go with the i5....something that would do what I needed it to do, and NEVER fail.

So I put this into an AsRock Extreme 4. Put my old hardware in there. Moved the drives over, loaded the drivers, and fired it up. Holy $^%t! All of that stuff on paper...forget it. What a kick. Real SATAIII is way faster than a SATAIII card. The! I felt like a kid on Christmas morning. This is a total computing experience. Again, I build cutting edge stuff for a living. So I'm kind of numb to this type of stuff. But when it was MY desktop flying around like that (Upgrade was from a core 2 quad).......I was an end user again, and a very happy one at that.

(just one tech note: You have to have a z77 or better southbridge to make all the newer stuff on the gen. 3 Intels to work)

The 3570k is one FAST CPU. And it's highly overclockable. I have my 3570k at 4.5Ghz right now and with this overclock I'm normally faster than a 3770k in most benchmarks, even multithreaded ones. And I'm a whole lot faster in single threaded benchmarks.

The reason I love the 3570k is because it's the most powerful CPU, per core, on the market. Meaning one of a 3570k's cores are just as powerful, if not more, than any other CPU on the market. The 3570k is even faster than a 3970x if your only using one core.

So in single-threaded programs, or programs that use 4 cores or less, and a lot of programs and 99.99% of games use 4 cores or less, this CPU will perform better than ANY other. The only time a 3570k's performance is less than a 3770k or 3970x, is when you start to use 5+ cores. Like in rendering and things of that nature. But even with rendering and multithreaded applications the 3570k is no slouch. In fact, a 3770k only gives you about a 20-40% performance gain, but only while using all 8 threads. 40% may seem like a lot but that's the absolute maximum it can be. On average the performance gain is around 25%.

This is exactly why I love this processor. For people like me who only game and surf the internet and use iTunes and do all the normal things people do, your processor absolutely can't get any faster than this 3570k can. That's just a fact. And for only around 200$ you can't beat the price/performance ratio. Sometimes it can be worth going with the 3770k, or 3930k, or 3970x, but for me, I wouldn't see any performance improvement with any of those. Sometimes I could actually see less, since the 3930k and 3970x are Sandy Bridge processors that aren't as powerful per core as the 3570k.

My advice is to buy this CPU.
