It really depends on what you want to do with the computer. The 965 BE is a core CPU with an unlocked mulitplier so it can be heavily overclocked. This makes it very good for gaming. Most games only use one or two cores anyway. The 1045T is a six core CPU and doesn't have an unlocked multiplier. With the right board it can technically be overclocked but only a few hundred Mhz it can't be overclocked to the same level as a Black Edition CPU. Also six cores is going to be way overkill for gaming because as mentioned already most games ony use one or two cores. So if you are gaming I would go with the 965 if you are doing more CPU demanding stuff like video editing, encoding or 3d design then I would go with the 1045T.
