This very old CPU is still more than enough to handle day to day spread sheets, word documents and other such workloads. Its only down fall is choppy google docs and windows (I have linux mint installed now). Its unfortunate we're forced to move on simply because MS Virus wants us to spend $1300 to run bloated software just to use a simple word processor.

11 years of perfect working. Now playing even MAFIA III with it on low. Really fond of it. All my tasks and games runs quite good. In 2019 and so many years of stable working I like it. It was the my best choice in them days.

Very old CPU but still working ..... And in this time we'll get him very cheap Only 4mb L2 cache slows him down
