Hi all. I recently put an AMD Radeon 7750 1gb low profile graphics card into my Dell Inspiron 660s. Along with upgrading the ram from 4gb to 8gb, I would like to upgrade the model's CPU as the current CPU inside is an Intel Core i3 (3rd Gen) 3220 / 3.3 GHz. I just want a few options to choose from that will fit inside, and work with the 220w PSU along with the current graphics card I have inside of it. Also, I am stuck with this build. I will look into a better, more expensive PC build in the future, I just want something that will be able to run things smoothly in the meantime.
