They all come with it except the OEM versions and Black Box versions... but stock coolers are garbage anyways... they keep it too close to the highest recommended temps... what you have is fine.. but what Maroon has is GREAT in performance far more superior processor...
but since you like AMD, heres whats wrong with what you have still The Phenom 9600 has the erratum bug so get the Phenom 9650 with the TLB Bug Fixed, the stock cooler can't cool for crap anyways so you could just get a 5000+ BE w/ the 780g and get a AF64 like I said before or get an e2200 with EP35-DS3L if you change your mind on Intel ..... Good luck running all this on most likely a low-end PSU
You really don't the money for a quad and it'll probably kill your PSU because its too weak.. so just get a bargain Dual-Core settle with that for a bit and then upgrade to a Quad another time
