I saw this one with a Core i7, 4GB RAM, two 500 GB HDDs, two Nvidia GeForce GTX280Ms in SLI configuration, 19-inch WXGA screen and other bells and whistles for sale at my local exclusive showroom.
There are 2 prebuilt config. found for both m15x and m17x in dell india website.
The base config for m15x comes around 1.2L and IMO is a very good config.
Even am planning to get that laptop. so do ping me if you have some offer or know someone through which we can get it with discount.
