It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
I would go with the Opteron. Having 8 physical cores will deliver much more bang than 4 physical + 4 virtual (through Hyperthreading), although the Xeon compensates slightly by having a higher clock rate.
Overall it depends on your load. If you are running low load 80%+ of your time, you might consider power consumption to be a priority instead. The Xeon platform will likely give you less overall power consumption.
