Not if you use the computer primarily for gaming. That Athlon II X3 is just fine for that. I would save up until the most powerful X6 is out. You won't see much difference in gaming from the Phenom II. I have a Phenom II X4 940 and I only got that because at the time, the Athlon II didn't exist and the Phenom I was known to have problems and was outgunned by the Core2Duo. The Phenom II X4 stood toe to toe with the Core2Quad and was much less expensive. Stick with the Athlon II for now. I think that the upgrade you're suggesting would be a waste.
