some laptops can; see: alienware, dell xps m1730, sager, et al.
Check out notebookreview.com for some decent user reviews; I typically don’t give too much credit to online benchmarks because they can vary so widely between different sources and such.
The inspiron 1720 (vostro 1700) is good, the older e1705 is also good. Other notable mentions would be the hp dv9500t series and the toshiba p100/p200 series has some good ones; heck just found this: http://www.toshibadirect.com/td/b2c/pdet.t…amp;poid=365595 which looks like a great deal to me (7900gtx 512mb ftw!)
