Hello guys, I am planning on getting a new CPU/GPU. Since my motherboard is not so great, I would like to know if it can actually limit the clock speeds of my CPU/GPU or limit them in any way. My motherboard is: H81M-S2PV

Specs:

i7 4790k
GTX970
2x4GB RAM
Corsair 550VS PSU

In addition: Would this PSU be enough for this specs? I think it is a pretty good quality because if I add up all the Watts on the box it is over 600.
