I'm a college student and am going to buy a new laptop and I was looking at these: j.mp/dellxps15in . My primary reason to buy is because in my previous laptop I couldn't play games. So I want this one to be a good gaming laptop. I'll be playing fifa, nfs on it, also assassin's creed, maybe skyrim and maybe crysis too. but other than that my major is computer science so I'll be doing programming, running virtual machines on it etc. I'll be watching movies as well. (Too bad they don't offer a fhd screen in india.) And all that's day-to-day stuff for me. No video editing but I do use photoshop sometimes. I was looking at second and last ones in that link. i7 seems to be a bit expensive but is it worth spending money looking at my usage? Also it's 2.2ghz while i5 is 2.5 and has more ram too. so please, give some advice...
