I have a board lga1150 socket with an intel i7-4790K processor. Task manager shows 8 cores/threads. All the i7-4790k processors I see for sale say simply quad core. What gives? I can't find any lga1150's that indicate 8 core...

Make and model of your LGA1150 socketed motherboard? BIOS version for said motherboard at the time of writing? What OS are you working with? Yes the i7-4790 has 4 cores but 8 threads due to HyperThreading. It's possible that your motherboard might be compromised if it's showing 8 cores for a processor that has 4. Please try and inspect the CPU's socket for any bent or broken pins as a cautionary note.

thank you for the replies. I believe it is showing 4 cores with 8 threads. Its running on an old win 2008 R2 server. In task manager I see eight process graphs. A standard quad core i7 4790K should replace the existing CPU.

OSes will indicate logical processors, or how many things they can stick a task onto. Since the i7 can handle two tasks at the same time, it shows up with 8 things Windows can schedule stuff on.

It's just easier to do things this way.
