[SOLVED] Does CPU -GPU throttle affect the GPU?

[MidoZido]

Hello guys
I am thinking about going for 580 8gb instead 570 8gb "as little difference in price and over 20 fps difference" till i upgrade my CPU I5 4690 to Core I7 a year from now on the HP 600 G1
Will the 15% CPU-GPU throttle affect the 580 in a wrong way, a lot of PSU power will be wasted? will the 15% throttle drop a lot of FPS or the 15 is the percentage the gpu won't work? what will happen throughout the year?

HP 600 G1 the 240watt PSU is not going to power a 580 so you need a good PSU as well I would think 600watt
