5 out of 5 eggsbetter than expected!

Pros: ok so i thought that this was going to be an upgrade from my fx 8350 but i had no idea it would be a HUGE upgrade. literally more stable fps accross the board any game i throw at it. you get what u pay for with this cpu hands down ball's to the power i've oc'd mine to 4.7 an couldn't be happier using an h55 corsair liquid cooler.

Cons: none that i can think of.
it won't make love to me?

Other Thoughts: like i said before u deff get what u pay for might seem like a lot to some but trust me when i say it deff perform's.

1 out of 5 eggsBEWARE - YOUR CPU MAY OVERHEAT

Pros: Haven't gotten to see many; games cause the CPU to reach 100 degrees C almost instantly, and causes my computer to crash to prevent damage.

Cons: While the CPU *can* reach speeds up to 4.4 GHz, you may never see them because it'll automatically limit itself once the temperature gets too high (which it did very quickly in my case). Now, this may not affect everyone (and probably won't affect most of you), but be aware that this chip has been known to have thermal issues. See this thread for more details:

1 out of 5 eggsDefective chips

Pros: Will work great until it fries itself.

Cons: I'm on my 2nd one of these that has the exact same problem of skyrocketing temps to 100c under any heavy load.
Operating at 80c under medium loads.
This is not normal, or safe.
Intel SHOULD be recalling these chips, but is instead doing a good job RMA'ing your chip if you have a problem. (I'm actually impressed at their process)

Visit the thread over on intel from people having the same issue: https://communities.intel.com/thread/54032?start=465&tstart=0

If you own one of these chips, pay very close attention to its temperature. It seems like theres a 33% chance you have a chip that is not overheating.
The other 2/3rds of the chips overheat severely.

I've had an overclocked G3258 and an i5-4690k in this same computer run fine with no overheating.

I'm shocked there aren't more poor reviews as this is a very common problem.

4 out of 5 eggsGood cpu

Pros: It's quick. I noticed an increased snappyness after replacing my 2600k with this. I really like the new features (like pciE 3.0)

Cons: Heat... I started with a modest OC of 4.6@1.245vdc. I than ran prime (28.5) and almost instantly jumped to 95-100. Of course the cpu began to throttle. At the time I was using an H100i. To fix the heat issue I delidded,used clu and replaced the h100i with a custom loop. I'm now at 4.7 @1.33vdc and the temps don't go above 85 c even when avx2 instructions are thrown at it.

5 out of 5 eggs

Pros: I had this CPU for a while now already and got a new one for my workstation. It's reliable and temperature is never too high.

Cons: Mine came with a smudgy heat paste. But it didn't appear to affect the temperature of the CPU at all nor affect the performance.

5 out of 5 eggsLightyears ahead of my last cpu

Pros: This is a must buy for any enthusiast out there. I have not upgrade my pc in quite some time and was used to the speed that I was running at. Now with the new Haswell, I am wondering why the hell I put up with my old cpu for so long. This is amazing and I would recommend it to anyone looking to build or upgrade.

Cons: None

Other Thoughts: I'm using the stock fan for now and i'm not having any issues with the temps at all. Plus, I don't see the point in overclocking this baby since it handles everything like a champ already.

5 out of 5 eggsSmoking fast batman

Pros: This processor is fast as the dickens. I haven't evened OCed it yet and it's tearing through everything I throw at it.

Cons: None, buy it.

Other Thoughts: I have read over and over that an i5 is all you need for gaming but for just a few more dollars I decided to upgrade. No regrets.
