I'm looking at getting a Toshiba X200 laptop. There're two models available here, the 15k and the 21k. They're both exactly the same except that the 21k has two 8600m GTS' running in SLI while the 15k has only one 8700m GT.
Which is the better option for gaming? A single, more powerful 8700 or two 8600s in SLI?
