I was looking to buy a 1.4ghz Athlon at www.bzboyz.com and I noticed that the site is offering it with an AHYJA core rather than the AXIA core for about 15 dollars more. There is also an option that states, "Send me AHYJA Core with 3rd Line which starts with: Y," for a few dollars more. I am assuming this core is better/runs cooler than an AXIA seeing as how it costs more, however I have no clue as to what the third line issue is about. Could someone please clarify both of these matters for me? Thanks...
