okay so i am planning to get a laptop and i can decide whether i should get the core i3 or i5. i really want to keep my budget on or close to $600. i dont really play games but i watch hd movies and multitask A LOT!!! when i say a lot i mean like about 5-6 programs at once. also, how is the i3-350m compared to the AMD athlon x2 64 5000+ 2.6ghz (desktop cpu), better or worse? thanks a bunch!!
