I currently have the Intel MB, D875pbz, running a 2.8c Northwood 800Mhz 478 pin CPU. I want to upgrade. Here is the list of processors from Intel's site that my MB supports. Supported Processors
The only one I can find on Newegg is the 3.0E. I guess they are not selling the 3.2 and 3.4 anymore. So, I'm guessing that going from a 2.8C to a 3.0E wouldn't be much of an improvement. Is that correct?
Also, the extreme edition processors are also on the list, does that mean dual core?
