hey guys i need help. i'm looking for a laptop since im going overseas to study so i hope to get some recommendations for laptops. looking for:

core i5 processor, hopefully the newer ones like i5 520
500GB 7200rpm hd
an upper level class 2 graphics card
4gb ddr3 ram
15.6-16" inch screen

gonna be using the laptop mainly for casual use, but im also gonna play games on it like crysis, risen, battlefield... so yeah i guess its gonna need a good CPU+GPU performance.

ive been looking at models and am interested in models like toshiba qosmio f60 and dell xps 1645 and asus n61JA... any reviews on these laptops or better alternatives? budget is 4.5k

thanks guysss
