Had mine since 2009. Overclocked the whole time at 3.4ghz. No issues. I recently dropped in a 1660 GPU and am playing Shadow of the Tomb Raider at 1080P on high settings without any issues.

Held up like a beast through 2019. But, definitely getting to be obselete, especially for modern AAA games.

Great lga775 CPU... Got it to upgrade an old 2009 optiplex 380, runs like a champ due to its large 12MB cache, just wish I could OC it to ~3GHz.
