hey,
actually i recently bought a dell. the only i5 theyre putting in their machines is the i5 2430m or something to those numbers. 2.3ghz, 4 cores with dell turbo up to 3gig
mines got 6gig, windows 7, dedicated graphics and let me tell you, its a little beast!
the chassis fans and air flow isnt the best and if i push it i really have to use my cooler but i've been using it nonstop for 3 weeks and so far i'm very happy, twin that with removeable covers
(i bought a customised insp 17r)
so far i've only tried Dragon age, WoW and fallout new vegas on this machine and it handles them all superb but if you do want it for gaming i would definatly recommend a heavyweight laptop cooler
