Summary: Well, with used CPUs you always hope that there are no problems, and once this one was installed I had no problems. This processor is in the machine I'm using to write this review, so obviously I'm quite satisfied with its quality and performance.
Summary: It does not do any better than the processor that it replaced. I have upgraded this old XP computer as about as much as I can upgrade it. Getting this processor was the last element in the puzzle. Off line, it is fine, just as the 1800 processor was, but on line, it functions about the same...slow.
