Hello. I currently have an AMD Phenom x3 8750 (2.4GHz) I want to upgrade to a better CPU but I want to stay within a $100 budget. I have been looking at the AMD Athlon II x4 620/630 and the Phenom II x2 550. I am just looking to see what else is out there for around $100 that would be better than my current CPU. If you have suggestions, please give them to me. Thanks!
