5 out of 5 eggsAwesome so far

Pros: This thing is fast! Running a 4.4ghz OC with a Corsair H105 cooler. Idling around 27C and topped out at 81C on Prime 95 stress test.

Cons: Pricey

5 out of 5 eggsVery Fast!

Pros: Fastest clock speed available.

Cons: I don't need the hyperthreading, but I wanted the fastest clock speed possible. If there had been a 4.0 GHz i5 I would have purchased that instead (assuming a lower cost of course).

Other Thoughts: I'm doing CAD work with this computer and a little gaming, Starcraft and Minecraft and the cpu temps never get above 45C with the stock cooler. I know others complain the stock cooler is wimpy, but for me its been just fine.

5 out of 5 eggsSimply outstanding performance

Pros: Performs super fast and cool with the stock cooler. Overclocking is a breeze (if you need to).

Cons: none yet

Other Thoughts: I heard a lot about this CPU running extremely hot. I have encountered the exact opposite with the stock cooler. I was going to buy a liquid cooler for it, but I have no need whatsoever. Temps barely breaks 50C after long periods of gaming.

5 out of 5 eggsSimply outstanding

Pros: Ultra fast and low temps with stock fan. Overclocking is a breeze (if you have any need to that is).

Cons: None yet

5 out of 5 eggsAwesome Processor

Pros: This thing is wonderfully fast, it has 4 cores, 8 threads, and runs like a beauty.

Cons: It isn't a 5960X. Seriously, none here.

Other Thoughts: When you upgrade from an AMD Athlon x2 220, you can REALLY tell the difference. Also, it was a little shocking to see the temps of this thing, cause that old paper weight did run stupidly cool. But, as far as I can tell, these temps are fairly average. Not to mention my room is an oven.

5 out of 5 eggsRuns great

Pros: At stock speeds, no overclocking - paired with a Cooler Master Nepton 140XL, and Noctua NT-H1 thermal compound, it's running idle between 28-31°C. Stress tested it with a few different programs... (not Prime95, I saw some things said about it not being the best thing to run with Haswell processors?)... and the highest I ever saw it hit was 62°C. Runs super quick paired with an SSD... I didn't have any interest in overclocking when I first was going to put this system together, but now I am thinking about dabbling in it a little bit.

Cons: None here.

Other Thoughts: I wanted the fastest system I could get right now without going super super overboard, this CPU was a fine choice for it.

5 out of 5 eggsBest Buy for 3billz

Pros: 4.0, unlock, Intel i7, Price.

Cons: None.

Other Thoughts: Left an Intel Core i7 965 @ 3.20GHz to get this one
Its not a life Changer but if you need to upgrade get this one. and don't fall for the High Prices of DD4 and Six or 8 core unless you have Boat loads of Cash. Sorry AMD Too much Heat and Electricity.
