sj.. can u help to hav a look 2nd n 3rd product??

high tech wow @.@

;p if based on ur explanation jus not.. the 13" (2nd) is better than the 15" (3rd)??

this two are gud for graphic N musical stuffs... longs to hav for doing 编曲.. ;p

u know the bottleneck. ;p

u can see how the rating for pc.. is to see the processor, ram, graphic card etc...

bottleneck for 2nd is graphic card, and for 3rd is... sure processor... just 2.0Ghz..

so need 取舍？ but i prefer the bigger size.. wil the processor really matter?

actually 3rd is ok de... 4 core of 2.0GHz, if not compared with 2nd one..

but is the graphic for the 3rd is pro~??

HD 6490M consider is good graphic, better than intel graphic. If say pro... hmm... the number is.. 6850 and above.

anyway 6850 is pro for desktop use... =p

6750M for note.. wow.. is very geng
