💡 How to pick a processor
What to look for:
  • Socket must match your motherboard (AM5 for new AMD, LGA1851 for new Intel)
  • Core count and clock speed for performance
  • TDP (wattage) affects cooling needs
💰 Budget builds: under $200. Mainstream gaming: $250-$400. Enthusiast: $500+

★★★★★Might be a defective CPU but dang this thing makes heat..
The seller did an amazing job. The item came even sooner than expected. The bad news is that I installed it in my previously flawless running machine. The reason I upgraded from my current i910900k is that I wanted to enable the NVME.2 4.0 on my SSD. I already had the drive and a Z590 motherboard so why not right? I put the new i9 11900k In and it started and enabled the 4.0 on my NVME. Yay right! Literally with in a couple minutes I received a watchdog timeout error. (This is caused by CPU cores failing to communicate with each other.) I called Intel tech support who was less than help full. I updated all drivers and still didn't work. I did notice my CPU temp was running over 100c. Odd because I have the best nactura CPU cooler they sell. I decided to upgrade to a liquid CPU cooler and that brought my CPU temp down to around 85c. That still didn't fix the time out errors. I put my old CPU back and all is happy. I ended up sending the i9 11900k back but at least my i9 10900k is nice and cool even at 45% overclock. LOL

★★★★★Great CPU
when i upgraded my desktop i decided to go intel core i9 this time. all my previous build was a 6th generation core i7 6700k. it ran fine but it wasnt up to running windows 11. so an upgrade was in order. besides, my old board was starting to fail. i originally bought a 10th generation core i9 10 core but that cpu was junk. there wasnt enough PCI-e Lanes to support my drives and usb devices. this is a limitation of 10th generation CPUs not a limitation on the board. my video card (RTX 3070) took up most of the available PCI-e lanes which took out most of my drives. so i went to the 11th generation i9 8 core instead. very happy with it. it solved all my PCI-e lane issues. i am able to run all my devices and drives. the cpu clocks at 5.3ghz stable i have water cooling installed. i see zero problems with this chip. its fast, its stable im plenty happy with the upgrade. the board is a MSI MEG z590 ACE Gold. i have 64gb DDR4 3200.
