When I open Core Temp, I notice that the frequency of my CPU will randomly jump between 4400hz, 800hz, 2200hz and etc. The same happens with the power, it'll jump from like 12W to 62W. Is this something to worry about? My CPU is an Intel i7-4790k and has not been overclocked.
Athlon II X4 760K (overclocked as high as this baby will go)
6GB 1600mhz
R9 270X
CX500 (or 600 if it is necessary) psu
Hopefully 1080p high/ultra 50fps? Or is that too ambitious...
