Hi all the sifus... need laptop recommendations here.

1. Preferred Brand : HP, but any brand also ok (preferably wont too fast rosak)
2. Budget : Up to rm2800
3. Usage : Basic websurfing, medium gaming, watching movies
4. Preferred laptop/screen size: 14 or 15.6 inch also can

Note: I'm now currently looking at:
1 - Pavilion G4-2205/2206/2207TX, i5-3210M + AMD HD7670M [2.19kg], 2GB ,500GB(5400rpm), W8, colors: white/red/black
or
2 - A45VS-VX028H, i7-3630QM + Nvidia GT640M@RM2899[2.4kg], 4GB, 750GB, W8
or
3 - A45VS-VX026H, i5-3210M + Nvidia GT645M@RM2199[2.4kg], 2GB, 500GB, W8

Which brand is more durable and trust worthy? (i'm studying in indonesia, so preferably got international warrantee). And is it worth it to get an i7 core if i dont do too much heavy gaming?

Thank you =)
