I bought this Intel 2600k, being a previous owner of the 4790k, I thought the processor might be okay. I figured for $20 what the hell why not. But man, I haven't even gotten the clock dialed in completely yet, and it already beats 6 of the Ryzen models in multi-threaded testing. I assume they take DDR4. I used CPU-Z as bench as comparison, they seem pretty reliable. Also, the 2600k beats every FX-series processor that was made. I remember when AMD was a joke.
The GPU and CPU are on water. In Time Spy in 3dmark never gets the card or processor over 40 degrees, and that's at 1493mhz GPU, and email@example.com CPU. Full on gaming I hit mid 40's. I have used DDR4 systems that felt like they performed sub-par.
Sometimes it's not about having the biggest, most overly priced processor money can buy. Although bragging rights are nice. This little processor blew me away because I got it for $20. Motherboard was $20 on offerup, and graphics card I already had.
