Dell Canada is now offering upgrades to the T8xxx and T9xxx series Penryn CPUs in its XPS M1330 laptops. The lowest grade Penryn version, the T8300, is available as a $100 upgrade over the T7250. That $100 will get you a 2.4GHz, 3MB L2 cache processor with SSE4.1 versus the T7250 at 2.0GHz and 2MB L2 cache (no SSE4.x either). That’s not even mentioning the improvement in battery life you should see. Excellent stuff.
