I've been looking at the AMD Phenom II X2 550 Black Edition as well as the AMD Phenom II X4 965 Black Edition for a new system i'm building. Yea, i'll be gaming, but what i'm having a hard time deciding and confused about is, the cores. Is it worth it for me to purchase the 965 at 179 when currently nothing will use the extra two cores?..sorry if i sound iggnorant, just want to get the best bang for my buck out of a AM3.. max i'm willing to spend is 189.99 on a cpu.
