What's the difference...

What's the difference between a

Intel Pentium® 4 530J Processor Prescott 3.0GHz and a

Intel Pentium® 4 530 Processor Prescott 3.0GHz ?

I checked the specs and they seem the same, but the J version sell 16 dollars cheaper on ZipZoomFly. Can anybody explain why this is?

Here's what i found on Intel's web site:

Intel® Pentium® 4 processor 530J° supporting Hyper-Threading Technology 90 nm, LGA775 1MB L2 3.0 GHz 800 MHz

Intel® Pentium® 4 processor 530 supporting Hyper-Threading Technology 90 nm, LGA775 1MB L2 3.0 GHz 800 MHz

they look the same, but the "j" shows this"

Execute Disable Bit ** Yes: 570J, 560J, 550J, 540J, 530J, 520J

Execute Disable Bit** Can improve protection against malicious "buffer overflow" attacks when properly enabled with a supporting operating system.

I don't know why its $16 cheaper, I'm not even sure what buffer overrun is, but that seems to be the way it is.
