Here's what Jim Cramer had to say about some of the stocks that callers offered up during the "Mad Money Lightning Round" Wednesday evening:

Nvidia (NVDA): "We want to own Nvidia. ... Fastest gaming chips, the best ones. You buy some. If it comes in, you buy some more. ... Nvidia is two thumbs up."

Dynegy (DYN): "Reports this week. ... We like Dynegy as an asset play, not as an earnings play. We think that the power plants are worth a lot more than they're selling for. ...We like [CEO] Bruce Williamson."

Spectranetics (SPNC): "Medical device company that I like. ... That group is hot. ... There are so many that are still down, but [Spectranetics] is a good, quality company."

Perfect World (PWRD): "If I'm gonna do China, I'm gonna do China Tel (CHA) and Baidu (BIDU), and everything else, I'm letting some other guy handle it."

Nymex (NMX): "Very valuable institution that I believe somebody would buy. ... Earnings are unbelievable. ... I wanna own your stock. The fact that it was up really big today is not enough to make me feel like we should ring the register yet."

Teck Cominco (TCK): "A lot of the resource stocks have come down. I like the stock very much."
