the GIGABYTE GA-970A-UD3 does not seems to have ucc feature
my total budget for cpu+motherboard is only 200$(or less if possible)
also when it comes to core to core (1 core of ph2 vs 1 core of fx) performance phenom 2 series have more powerful cores
some compressors like uharc use only one core and their are other applications too that use only one core
also except chitset and socket other features are same
i have added more info on main thread
First of Phenom II is not faster than BD. BD is misunderstood. Windows 7 doesn't even recognize it's architecture, therefore doesn't know how to place the threads in order, and it places them randomly, which is why Win7 benchmarks are so bad. Windows 8 will bring 20% more performance.
Either way, whether you want to go BD or not, there will be newer BD's, there is also Piledriver and god knows what else. So if you don't ever want to upgrade the cpu, fine, then go with whatever you want and buy one of those old overpriced 8XX series chipsets.
I gave you the BEST suggestions in the $100 range for WHATEVER cpu you decide on. Take it or leave it.
