Ok. So ive been lookign at alot of computers. Moslty at Alienware and ones at newegg.com. Ive been also wondering that is the Sentia for alienware a good gaming laptop. Ive configured the Area-51 and the sentia for the same configs and they both cost the same. The one that im most interseted in is the Sentia because it only weights like 4 pounds. So my question is why is the Sentia not considered to be a gaming laptop? I want a laptop that i can play games on and also do work, like college stuff. So is there such a laptop? Please tell me if there is.
