Should i get this m17xr3?

Ok, first off, good laptop, outrageously overpriced. I would not come anywhere near paying that price. yes, you are getting some of the best stuff for 10x the market price. Also ,alienware is now made, by Dell, so you are gonna have the same problems everyone else has with Dells, unfortunately. I would go look at a higher end Asus G series that has basically the same stuff ecxept they all have either the amd 5870m or nvidia geforce GTX460m. This option will save you about $1000 truthfully. Go look them up on Newegg, they are really reliable in my past experiences with them.
