Alienware 18 :
The Alienware 18 is a very flexible system when it comes to possible configurations. The base $2,099 model isn't exactly going to set your world on fire, with an Intel Core i7-4700MQ processor, dual GeForce 765 GPUs, no SSD, and only 8GB of RAM. On the other hand, you can get a nice SSD/HDD combo and 16GB of RAM, and make your major investment in two GeForce 780M GPUs for around $3,500. Check the configuration options carefully, as Dell/Alienware always seems to be deeply discounting one upgrade or another on a rolling basis.
