Both are pretty lousy investments to be honest. The days of the stock exchange being a way to legitimately make a fortune passed quite a while ago. Might as well shove it in a bank or flush it down the shitter in most cases. With stocks so low, it's a potential to make some decent cash, but it's also far too risky to get my recommendation.
CDs and games devalue like a motherfucker. In 10 years time, they won't be worth the disc they're printed on unless you can get your hands on something super special. But I highly doubt that.
If you want a sound investment right now, minerals are where it's at. Gold is kind of the standard, but all minerals have been doing pretty well.
Medical care is also a solid one. The world is incredibly health conscious and with an aging population it's going to get pretty damn good. Consider senior healthcare and the like specifically. Retirement homes also work.
Also, not a bad idea to go with real estate. With so many foreclosures and the like, there's some good opportunities to snatch up some property on the relatively cheap. It's pretty rare for someone to lose cash on investing in land unless they fucked up hardcore.
