Verified Purchase
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)

First off, let me state that I bought mine through Micro Center because they were offering the mobo I wanted in combination with this CPU when it first dropped for $280 as a package. However, I highly doubt there will be a big difference in the chip based on where you bought it.

This chip is out of this world. I paired it with a Z77 mobo and it FLIES. I've managed to successfully OC it to 4.6 GHz on air cooling (Cooler Master V-8) with temps ranging from 20C idle to 64C load. That sounds high, but the TJMax for this chip is 105C and it's safe to push up to 90C. I've still got enough room to MAYBE push 4.7 out of this, maybe. Now note, you WILL NOT be able to push this chip much beyond 4.5 GHz without some serious cooling solutions thanks for Intel's decision to use paste instead of solder. There is a major voltage/heat wall at 1.34v that will stop you in your tracks and the temps start rising fast at about 1.28-1.3v. However, pound-for-pound, this chip is worth it in both my opinion and reviews over the last generation simply because of that native USB 3.0 support and PCI-E 3.0 support. It will run neck-and-neck with a OC'ed Sandy Bridge, but offer the new supports. Both may not be used heavily right now, but I'm future proofed for at least 1 1/2 years minimum. Why not get the same performance with new toy for slightly more price?

I do not use my system for heavy media processing so I cannot comment on that, but I do use it to see how far I can push the system and for gaming. Just for an example, I'm running BF3 (which is very CPU intensive for a MP game) under ultra settings and only use 68-72% of my CPU potential. My previous AMD 955 BE was under 100% the entire time and never let down.
