Intel Core i7-9700K Desktop Processor 8 Cores up to 4.9 GHz Turbo unlocked LGA1151 300 Series 95W

Have had this for a year or two now in my upgraded gaming PC. Have not experienced any issues with performance, shipping, nor installation.Be sure to pair with a compatible motherboard and similar quality GPU if you will be gaming to mitigate bottlenecks. I personally have an nVidia 4060Ti.

I had an i7 processor and/or motherboard go bad. It still worked if you set it to a single core, but the multicore stopped working. I had way too much stuff setup on the computer and didn't want to buy a new computer and have to reinstall hundreds of applications and move all the data, so I decide to fix the existing Lenovo Legion computer.Rather than try and figure out if it was the processor or motherboard that went bad I bought a replacement motherboard from Lenovo (only place I could find it) and this i7-9700K.To my knowledge Intel no longer produces the i7-9700K processor and I needed to have this exact one since it was going into a legacy motherboard, so I had to purchase a used processor.The i7-9700K came in a plastic processor package and that was placed inside of a small, padded, mailing envelope. It arrived in great shape, no issues there.I was a little leery of it not working but I pulled out the old motherboard and processor but in the new ones and the computer started up and has been working great.The only problem that I've had, which is not the fault of this processor, is that putting in a new motherboard causes all of the authentication for Microsoft Office applications to fail. Still trying to get that resolved. Really hoping I don't have to uninstall all Office apps and reinstall. My other applications that I've run so far had no issues.The processor arrived quickly and has been running great so I'm happy.

Installed this on a Z390 Gigabyte Aorus Master, under a Corsair h115i with Conductonaut like Tom's Hardware said to do. Out the box it's running 4.9 for 1 core, 4.8 for 2-4 cores, and 4.7 for more than 4 cores. Without tweaking any settings, voltages are in the mid 1.2's. In general gaming use, temps run in the mid-50s with this rig, but the XTU benchmark can push them into the 60s. A few half-hearted attempts at overclocking reveal that this chip, like many of its kind, isn't particularly happy with AVX over 4.7, and some of the cores seem more susceptible to this than others. Still, I couldn't get it over 80 degrees C; platform instability happened first, at 5.1 with an AVX offset of -2. (5.1 at -3 ran at 1.4 with not much other tweaking required). Combined with a couple Samsung NVME drives (512G Evo and 1TB Pro) and some 3200 GHz LED RAM, boot times are superfast (with Fast Boot on) - blink and you miss it.I was able to push a 7680x1440 three-monitor rig to 60 fps minimum in GTA Online; average framerates were in the 90s, though nVidia Surround had me limited to 60 Hz. The same 1080Ti could only do 23 fps minimum with my prior rig, which was Z77/3770K@4.4 GHz based.Nearly any other game I can push my ROG PG279Q to its full framerate of 165 Hz without difficulty. I like to play Rocket League at 250 fps to minimize input lag and was pleasantly surprised to find that I could keep it over 200 and still get what that game calls "quality" graphics on both the single-monitor and triple-monitor setups. I'm old enough that I'll take whatever edge I can get!Install was a snap, watch a video if you're worried about it. Computer booted fine the first time I turned it on - if you can turn a screwdriver you can build a PC. And this processor is the one to get - I expect to be future proof for many years!

so got this about 3 years ago now thought i make a review on it so the i7-9700k is a great cpu i have not had problems with no overheating no problems i have built it a gigabyte z390 designer motherboard got a NZXT Kraken Elite 360mm for cooling and its still going strong i would recommend this cpu for beginners because its a budget friendly cpu.
