how would a A8-6600K work and will i need a new cooler or will the one i have work/will it come with one.
yes i am still using integrated i dont have the money for a discrete gpu
If you get the A8-6600K new or used in-box, it will come with a heat-sink/fan for the 100W (TDP) APU. Your old cooler from the A4-7300 is only safe up to 65W. The A8-6600K will come with a faster clocked quad core and a slightly faster iGPU.
I would recommend getting a discrete gfx card first, but prices are crazy right now. What are you trying to improve on? Gaming graphics or Better multiplayer response?
