I was in Intel camp for about 10 years and upgraded three times during that time. Last year (time to upgrade again) I switched to AMD. The thing was, no matter how I calculated, Intel route turned out quite more expensive than AMD at similar performance.
Now I'm running 5900X on 110€ motherboard, cooled with 50€ CPU air cooler. And yes, I get full performance: max 82-83°C at ~22°C room temperature. I don't give a crap if Intel is 8fps faster in some game (is all Intel can show right now)... and I don't want to turn my PC into water cooled nuclear plant to get performance.
But who knows.. in five years, I will maybe switch back to Intel again
