Hey,i was just giving u an advice buddy,the final choice is urs.Until last month I too was under M17x r3 fever,but my friend & even my uncle from us advised me not to go for Alienware.They seem great but they dont last long and after spending so much on a laptop u would want it to work well atleast for 4yrs.
Anyways whats the final config u made and the price.
Do let me knw when u get it.
