Re: new here and big AMD question to start off with
The 955 is definitely a Black Edition chip. The 955 is also a quad-core whereas the 720 is a triple-core. Almost all AMD chips will over-clock, From the Athlon 64 to the bulldozer. The 720 bundle is generally better spec in every area other than the chip. It's a shame you can't get the 720 bundle and put the 955 in it lol. Also neither bundle specifies the motherboard it uses, which is always annoying.
EVGA SLI Micro Z68 // Intel i5-2500k // 8GB Corsair Vengeance 1866MHz // Overclocked 2GB MSI R9 270X // Corsair Carbide SPEC-03 // Kingston Hyper-X 120GB // 2TB WD Green + 500GB WD Black
