Question

Just regular above quality photos for Facebook and normal things.

Answer

Facebook images are usually displayed at around 720×540 pixels. That is about one third of a megapixel, so for that use, anything you can buy is overkill in terms of megapixels. This is perfectly fine for almost all online display, and will even make decent small-sized prints.

However, megapixels do not accurately represent image quality. The answers to Why do some DSLRs have fewer megapixels than some pocket cameras? provide some of the explanation as to why. You can't really use that as a way to make your decision.
