I know your a multitasker, and only want the AMD, but is it because of this?
"I am sticking with my motherboard and want the 64bit CPU"
You can now get a Pentium in 64 bit, though yeah, it'll probably be too expensive at the moment.
I'd help with the other parts, but none of those links work I'm afraid:
We are very sorry, the page that you requested does not exist.
"Newegg.com has been undergoing many improvements recently, which required some pages to be moved. "
Could you possibly find them again?
Hope I can help
