Hey everybody, thanks for your very helpful advise. Just for the record, in my original post, I wrote the wrong information on the chip being a 2.8c. My mistake! I should have said it was a 2.8 with c-1 stepping. And your advise was sound on not throwing away $150 on a CPU that would provide virtually no speed increase, and the socket 478 being obsolete. Instead, I'll redirect the $150 bucks into a system upgrade kitty. It will take awhile, but it probably will be worth it. Again, thanks for all your insight.
