Get's pretty hot after 5ghz haven't had it run above 61c yet on 5ghz after a 5 hour stress test.

Does what Intel says it does. Be super quick at gaming. Really incredibly fast, there's been complaints about temperatures but mine seems pretty cool.

Best gaming performance money can buy.

If you're into both gaming and other CPU intensive tasks, this processor is fantastic. I would say if you're looking into strictly gaming, especially beyond 1080p, this CPU may not be for you with its high price-tag.

Expensive, but a great CPU. Mine can get up to 5.2 GHz for benchmarking, or 5.1 GHz for 24/7 use at a reasonable 1.30v or so.

Performance is excellent. Overclocked to 5.0 GHZ on all cores using 1.32 volts and Corsair H100i V2 cooler.

Processor is and was still overpriced when I bought it for $579 plus tax from Newegg.

Beats nearly every mainstream processor on the market right now but the price is terrible. I couldn't decide between this and 9700K so I just went for it. I'm glad I did though.

Handles heavy load, stable temp under load as well. Very good CPU

3 stars for now. CPU worked on first boot to bios. It somehow died when I went to reboot and install windows. CPU failures are so infrequent, but it seems there are several others who have experienced random and sudden 9900k failures.

Edit: new 9900k works like a dream. Temps are reasonable. 4star for price and holding hyperthreading hostage. Next stop, 5ghz.

What can I say: it's the best Intel CPU for development, balancing cost, features and flexibility for overclocking. In development, the more cores and threads, the better for compiling, building, encoding, etc. This CPU is the latest/greatest from Intel for such (without treading into exotically priced CPUs). Plus I like to use the included graphics capabilities of the chip, instead of buying another video card.

OC CPUs to 5.0 GHz and RAM to 3200 MHz, running between 25°C and 59°C average on CPUs with my development workloads, so far. Really not stressing system, so fans haven't spun up.

I highly recommend it for software development.

This chip can really spit out juice when it's overclocked, I've had great performance with it and am really happy with the purchase.
