Re: new computer,few questions.....
The 8600 requirements are relativly low, it needs a 300-350w psu though, so urs wont be good enough,so yeah upgrade if u can.
If u have decent cooling in the pc anyway, its not always necessary to use an aftermarket gpu cooler, i dont on my 7950gx2, i do however increase the fan speed. Id def get the after market cpu cooler tho,i have the zalman 9700 led and its great, helps overclocking and keeping heat down.
Just noticed its a GT super so that would be a 350w psu needed, not sure of the 12v railing rating required though.
