Summary: We recently upgraded our database programs and do alot more work online. Our computers were getting noticeable slower at some tasks, one a Dell Optiplex 740 with an Athlon II X2 and the other a custom build PC with an Athlon X2. The cpu's both worked fine in these old systems.
Summary: Works great. Plug and play. No problems at all, has been running flawlessly for a month now. This processor is about the best bang for your buck that you will find. Easy to install. You can watch a youtube video just before installing it if you have any reservations.
