This is a tough decision. The Crossfire 5870's in the Alienware M17x provides the best graphics. The Covet Precision M6500 only has a Quadro FX 5000M but has a better screen, 16GB of RAM, 3 256GB SSD's and a FIPS fingerprint reader. I didn't go with the 32GB RAM option because it will delay your shipment date. Even so, I personally think the Precision looks better and would go with that. Maybe you can provide more information on what you really need?
