yea, the Pentium D, does everything that the AMD Opteron Dual Core does, plus more... The P-D is also faster and can run an average of 38 programs at the same time with out having any kind of lag on the computer. On top of that, you can even run 2 anti-virus scans and 2 anti-spyware scans and still not have any lag, that is where the hyperthread comes into play! So right now, the Intel Pentium D processor is the best one out there, only problem is that it costs $4000.
