Summary: This is a week old but so far it's worked nicely. It's a tough little SOB because when lowering the enclosure after gingerly placing it into the mobo, the housing fell on it in a way that it wasn't supposed to (the little lever on the side isn't exactly fool proof, I learned...) but after running Prime95 overnight (which, for my purposes, is plenty of time, though some people recommend 24 hours) it has held up nicely, no errors or anything.
Summary: Very powerful processor at a great price! I bought this product in part because I was afraid it would soon become unavailable due to the emergence of the new Haswell processors. I bought it shortly it went up in price from $274.99 to about $285. Shortly after I bought it, it went back down in price again to $274.99 (probably to match Newegg's promotion during that time period). I will try to see if I can get a refund in the price difference.
Summary: When running software such as photoshop and photomatix, the cpu temps were 60 C and spiked to over 80 C with stock cooler and no overclocking. The temps on all cores even spiked to 95 C while merging a 9 exp HDR image in photomatix. I know this is still below the max rating but 90+ is beyond my comfort zone. After installing CM 212 plus, temps are back down to 25 C and spike to 50-55 C.
Pros: Blazing fast CPU from both a gaming and photo editing perspective. Debated between this and the 3770K model, but since I will not overclock, decided to save the money and go for the 3770.
Cons: The stock heatsink and fan included are absolutely horrible. Other reviews mention this but it is worse than my worst expectations. I had to knock an egg off for that. See comments.
Summary: Unless you plan on overclocking this is a great processor to get great performance while saving a few bucks. Make sure you have a well vented case or an aftermarket cooler as the processor runs very hot.
Summary: The CPU itself is great. The wires on the stock CPU fan are a bit tight. Initially, I thought this was the loudest fan I'd ever heard. Seeing my distress, my nephew pointed out that the fan blades were catching the wires. After some adjustments, made difficult by the tight wires, the fan was more than acceptable. Note to Intel, better placement of the wires, or a little more slack for adjustment, would make life much more pleasant.
Summary: This is a great CPU for the average user. Fantastic speeds and just works great. The stock heatsink leaves a little to be desired, but the 212+ from Cooler Master can be picked up cheaply ($20) and allow for plenty of room for overclocking. However, if you're looking for OC'ing, pick up the 3770k instead. For everyone else, this will easily suffice and succeeds as a very high-end CPU for intensive work.
Pros: Fast Processor, Reasonably Priced, OC'able
Cons: Lack of Unlocked Multiplayer (See: 3770k), Lackluster Stock Heatsink
