These two processors cost the same, except the Pentium D 945 is 3.4ghz lol, i mean thats a good selling point, when i go to sell this ill be like yeah, its got 2 3.4ghz processors, and nubs will be like yay w00t. But i dont know which actually performs better, except the X2 only has 1mb of cache, vs the 4mb of the pentium d. I am wondering which will actually perform better.
